AFRL, Industry to Launch Fourth-Generation Spacecraft Thermal Control

Oct. 25, 2021 | By Amy Hudson

The Air Force Research Laboratory will soon have the first operational oscillating heat pipes flying in space, marking the first operational application of fourth-generation spacecraft thermal control. The technology was previously tested aboard the secretive X-37B reusable spaceplane, AFRL said.

The laboratory is partnering with ThermAvant Technologies and its system integrator, Maxar Technologies, to develop and deploy the technology, which is lighter weight, “highly-efficient,” and more affordable than the thermal management subsystem used today, according to an AFRL release. Satellites need to dump heat generated from their own electronics and from the sun to avoid ruining their systems, including optics and atomic clocks.

“Oscillating heat pipes have flown in space before, but now OHPs are being relied upon to serve a mission purpose,” said Jon Allison, the thermal thrust lead for the Spacecraft Component Technology Branch of the AFRL Space Vehicles Directorate. “The on-orbit operation of OHPs marks an important milestone in the technology transition.”

AFRL began looking at OHPs in 2008. ThermAvant, based in Columbia, Mo., developed the OHPs through a Defense Department Small Business Innovation Research contract, and AFRL’s Space Vehicles Directorate designed and built the hardware, along with a few other companies, for an orbital test in 2012. The technology flew again aboard the fifth X-37B Orbital Test Vehicle flight in 2017, which stayed in orbit for a record-setting 780 days.

The heat pipes themselves are static, but the fluid inside oscillates causing the heat transfer, according to the release. “The OHP is a simple, wickless heat pipe capable of rejecting more than 200 times the maximum heat load of an axially grooved heat pipe, and transporting more than 45 times more heat than copper,” according to AFRL.

Allison said this new technology could be used in space for the next 20 years.

“We have seen how every generation heralds a new era in spacecraft thermal control by introducing a new, revolutionary technology,” Allison said. “The first generation used only thermal conduction, the second generation introduced heat pipes, and the third generation introduced loop heat pipes. The advent of each new generation enabled larger, more powerful spacecraft.”

However, Allison predicts the fourth-generation technology will do the opposite, focusing instead on “smaller and more powerful spacecraft.”

More than 53,000 Afghan Evacuees on US Bases as Pentagon Monitors Readiness

Oct. 25, 2021 | By Greg Hadley

More than 53,000 Afghan evacuees remain at eight military bases throughout the continental U.S., but despite the resources needed to support that population, the military’s readiness has not been adversely affected, the Pentagon’s spokesman said Oct. 25.

Defense Department Press Secretary John F. Kirby, speaking during a press conference, detailed the distribution of Afghan special immigrant visa holders, applicants, and other evacuees across geographic combatant commands, with the vast majority in the U.S.

“In the Central Command area, there are just over 3,000 Afghan evacuees. In the European Command area, there is 463. And then here at CONUS bases under NORTHCOM’s authorities, there are 53,157 at eight locations,” Kirby said. “Thus far, 6,689 of them have been released for resettlement, and they’re on their way to their new lives.”

At the start of September, U.S Northern Command commander Gen. Glen D. VanHerck told reporters 25,000 Afghans were at the eight bases, which include Joint Base McGuire–Dix–Lakehurst, N.J., and Holloman Air Force Base, N.M. VanHerck also said the bases would eventually be able to house up to 50,000 as they built up infrastructure akin to “eight small cities.”

Nearly two months later, Kirby acknowledged the time and effort it is costing the military to maintain the infrastructure to support the evacuees and said the DOD continues to monitor for any impact on readiness.

“We’re very proud of the role that we’re playing and of the terrific job, the compassion that our men and women are showing every day—not just here at home but overseas—and in making sure that these evacuees have a safe and secure environment to live and to work on their process towards citizenship,” Kirby said.

“But obviously we also have a commensurate responsibility to defend this country, and one of the things that we’re constantly reviewing is the degree to which our readiness to do that is being affected by this fairly sizable mission set. And we don’t believe now … that our readiness to defend the nation is being adversely affected, but clearly there are assets, resources, time that are being devoted to this, that are in some cases not being devoted to other things, and so we’re watching that very closely.”

Kirby also reiterated that all evacuees have to pass through a security screening process and receive the necessary vaccines before being transported to the U.S., where they will eventually be resettled in communities. The Associated Press reported Oct. 23, however, that a number of Afghans who “triggered potential security issues during security vetting” have been sent to Camp Bondsteel in Kosovo.

“We’ve surged resources and we deployed some additional personnel from relevant departments and agencies overseas to Camp Bondsteel to effectively vet individuals who require further processing before onward movement, and there are a range of Afghan evacuees at Bondsteel to include many Afghan families, women, and children who we’ve definitely prioritized being able to keep them together,” Kirby said, adding that the U.S. had agreed to relocate all Afghans from Kosovo within 365 days.

US Supports ‘Stronger and More Capable’ European Defense, Austin Says

Oct. 22, 2021 | By Greg Hadley

The U.S. supports “a stronger and more capable” European defense, but that defense should not duplicate the functions and capabilities of the NATO alliance, Defense Secretary Lloyd J. Austin III said during an Oct. 22 press conference in Brussels.

Austin, speaking at his first in-person NATO Defense Ministerial, was responding to a question regarding recent efforts by some European Union members to expand the bloc’s military units with a rapid reaction force.

Germany, Finland, the Netherlands, Portugal, and Slovenia proposed the initiative, according to German broadcaster Deutsche Welle, which would include “space and cyber capabilities, along with special forces and air transport.” French President Emmanuel Macron has also backed the idea of a European army, according to the BBC.

While Austin demurred when asked what kind of capabilities he’d like to see the EU develop, he did say that “we certainly support a stronger and more capable European defense, and one that contributes positively to the trans-Atlantic and global security that’s compatible with NATO.”

Austin’s comments echo those made by President Joe Biden during a phone call with Macron last month—a joint statement issued afterward said that “the United States also recognizes the importance of a stronger and more capable European defense, that contributes positively to trans-Atlantic and global security, and is complementary to NATO.”

Both Austin and NATO Secretary General Jens Stoltenberg said Oct. 22 that the EU and NATO should ensure their capabilities work together, instead of duplicating each other.

“We’d like to see initiatives that are complementary to the types of things that NATO is doing,” Austin said. “So we see, hopefully, these two organizations working together to enhance security in the region and ensure that that trans-Atlantic bond remains strong.”

“What is needed are more capabilities, not new structures,” Stoltenberg said. “Our trans-Atlantic alliance remains the bedrock for our security.”

The EU and NATO share 21 common members, out of 27 and 30 total, respectively. Another four NATO members are currently candidate countries to join the EU. According to the Congressional Research Service, U.S. European Command has more than 70,000 personnel permanently stationed in the region.

Biden and Macron’s discussion of European defense last month was prompted by the AUKUS deal, with the U.S., U.K., and Australia agreeing to a pact highlighted by the sharing of nuclear submarine technology with Australia. That agreement was widely interpreted as an attempt to counter China in the Indo-Pacific but angered France, who had a previous deal with Australia for submarine tech.

Coming out of the Defense Ministerial, however, Austin said the U.S. and its NATO allies remain dedicated to contesting China’s influence.

“We’ve seen increasing interest in our allies and partners to ensure that they engage our partners in the Indo-Pacific and work with our partners to ensure that we collectively work to ensure that the Indo-Pacific area, or region, remains free and open, and the international rules-based order remains in place here,” Austin said.

While Austin and other top defense officials have continually stressed China as the U.S.’s pacing threat in recent months, Austin’s visits ahead of the Ministerial, to Georgia, Ukraine, and Romania were largely focused on the threat of Russia.

“I think what President Biden wants out of any kind of relationship with Russia is predictability and stability. And I think with nations like ours, I think that’s very, very important,” Austin said Oct. 22 in response to a question about Russian deterrence. “Again, we want to make sure that we continue to support our allies and partners in their desire to protect their sovereign territory and their desire to increase their resilience. So you’ll see us continue to do that. You’ll see us continue to work with our NATO allies and partners.”

New Hampshire Guard Selected as U.S. State Partner to Republic of Cabo Verde

Oct. 22, 2021 | By Amy Hudson

The New Hampshire National Guard will be the official U.S. state partner to the Republic of Cabo Verde, an archipelago off the northwestern coast of Africa, after a “highly competitive” months-long selection process, the Guard announced Oct. 21.

“This is great news for New Hampshire,” said Gov. Chris Sununu in a release. “We are safer as a state and a country with strategic partnerships across the globe.” The New Hampshire National Guard has had a similar relationship with El Salvador since 2000.

The State Partnership Program launched in 1993 following the end of the Cold War, as former Soviet-linked militaries sought American ties. Latvia wanted U.S. help to adopt a citizen-soldier model, similar to the U.S. At the same time, the U.S. government was looking for a way to expand military-to-military cooperation in central and Eastern Europe without threatening the new Russian Federation. The National Guard seemed like the obvious choice.

The program now includes 83 partnerships, or about one-third of the world’s nations. New Hampshire is among several state Guard organizations that partner with more than one country.

“We have the experience and knowledge to build a strong partnership with Cabo Verde,” said Maj. Gen. David J. Mikolaities, adjutant general of New Hampshire, in the release. “Beyond the shared benefits for Cabo Verde and New Hampshire, we have an opportunity to play a strategic role helping to maintain stability in the region.”

The partnerships have helped some nations become NATO members, the release said.

Rep. Chris Pappas (D-N.H.) advocated for New Hampshire’s selection. “This strategic partnership will support our national security by building lasting alliances and ensuring our two countries can work alongside each other to counter transnational organized crime operations,” he said. “I’m grateful for the role the NHNG plays in keeping our communities safe and look forward to the opportunities this partnership will bring our state.”

Cabo Verde, which is located about 300 miles off the coast of Senegal, is a seven-hour flight from Boston’s Logan International Airport. The island nation gained its independence from Portugal in 1975. Its military, which consists of a National Guard and Coast Guard, focuses primarily on combating international drug trafficking.

Kessel Run Signs ‘Historic’ Agreement With ACC. Here’s What It Means

Oct. 22, 2021 | By Greg Hadley

As part of a continued overhaul of the Air Force’s approach to software acquisition, the service’s Kessel Run software factory signed what officials called a “historic” agreement with Air Combat Command.

The user agreement, signed Sept. 30 and announced Oct. 20, marks the first time one of the Air Force’s software factories has signed such a deal with a major command.

In previous years, Kessel Run worked with ACC and other agencies mostly through the Middle Tier of Acquisition process, Kessel Run commander Col. Brian Beachkofski told Air Force Magazine in an interview. However, that process, designed for capabilities that can be rapidly prototyped or fielded within five years, still wasn’t quite right for the software that Kessel Run was developing.

Acting Air Force acquisition boss Darlene Costello then moved the detachment to the DOD’s Software Acquisition Pathway, first unveiled in October 2020.

One of the requirements in the Software Acquisition Pathway’s process is a signed user agreement, leading to the announcement between Kessel Run and ACC.

“What’s most important about this is it highlights an area where the acquisition structure and the acquisition roles are making substantial changes to enable software delivery,” Beachkofski said. “There was always this tension in JCIDS and waterfall and static requirements, that it’s hard to do software development for a changing world in a structure that’s built to deliver aircraft and large systems with 20-year acquisition timelines.”

Under the new agreement, the relationship between the MAJCOM and the software factory has been redefined so there is “oversight defined in a way that’s relevant to software as opposed to hardware,” Beachkofski added.

Also required in the Software Acquisition Pathway is a Capability Need Statement, which will be updated yearly, as opposed to just once. That’s necessary, Beachkofski said, because the goal with software is to constantly update and change as needed.

The new user agreement with ACC covers four programs under development, with the largest being the modernization of the Air Operations Center Weapon System program. The Kessel Run All Domain Operations Suite constitutes roughly 80 percent of Kessel Run’s budget authority, Beachkofski said.

KRADOS, a suite of software programs aimed at overhauling how ACC approaches command and control planning and execution, has been in development for some time now. In April, under the old Middle Tier of Acquisition process, it was declared a minimal viable product.

“So Block 20 is the new system that we’re developing, and the software within it are a suite of applications that enable the AOC operators to do their workflows more efficiently and have a common data layer behind all of them,” said Beachkofski. “Essentially, one of the issues with the [old] system is it’s a system of systems where everything is tightly integrated. So it’s hard to make updates and changes to the system and modernize it. So we’re moving to a more modern microservice architecture, where you can make changes, and they’re not tightly coupled with all the other systems so you can keep it modernized more affordably and easier.”

The 609th Air Operations Center at Al Udeid Air Base, Qatar, became the Air Force’s first AOC to operationally use KRADOS to build an air tasking order in May, and the system was once again used during Operation Allies Refuge, which included the noncombatant evacuation operation out of Kabul, Afghanistan, Beachkofski said.

Currently, the 609th is using KRADOS to plan operations for U.S. Air Forces Central. By March 2022, Kessel Run hopes to have the actual execution of air tasking orders operating on the system as well. After that, the goal is to roll it out to all the AOCs, Beachkofski said.

Austin Visits Romania Ahead of NATO Summit, Hints at Future Black Sea Deployments

Oct. 21, 2021 | By Abraham Mahshie

Walking the flight line occupied by Blackhawk attack helicopters and American troops on rotation at the “MK” air base in Romania, Defense Secretary Lloyd J. Austin III highlighted the strategic value of one of NATO’s newest members Oct. 20 ahead of NATO defense ministerial meetings in Brussels Oct. 21-22.

“Romania is one of a handful of NATO allies that hosts a significant number of U.S. rotational forces,” Austin said after meeting Romanian Defense Minister Nicolae Ciuca.

“Security and stability of the Black Sea are in the U.S. national interest and are critical to the security of NATO’s Eastern Flank,” he added. “Russia’s destabilizing activities in and around the Black Sea reflect its ambitions to regain a dominant position in the region and to prevent the realization of a Europe that is whole, free, and at peace.”

Romanian security analyst Iulian Chifu told Air Force Magazine that Russia uses information warfare, electronic warfare, and the militarization of Crimea to threaten NATO’s Black Sea allies and partners. Russia also regularly buzzes, or flies low, over NATO commercial and military vessels in the Black Sea.

“We all understand it’s a matter of projection of force,” Chifu said of the growing Russian aggression.

“The problem is Crimea—which according to Russia is part of Russia, and they need to enforce that at some levels that are far overpassing the capacity even to attack anytime Romania, Bulgaria, and Turkey,” he said, naming the three NATO Black Sea partners.

Mihail Kogălniceanu Air Base near the Black Sea coast, known as “MK,” has received millions of dollars in European Deterrence Initiative investment and hosts several hundred American troops on continuous nine-month rotations. The air base is at the southeastern edge of NATO, just a few hundred miles from Russian-occupied Crimea.

In public comments, Austin said Romania plays a “key role” in U.S. freedom of access to the Black Sea.

The Romanian Defense Department has slated $135 million for investments at MK and training facilities at the nearby Capu Midia training area. MK has already been used as a waypoint for American deployments to Iraq and Afghanistan, where 27 Romanian troops died in combat over the 20-year conflict.

In part, Romania’s investments have been made to lure additional American troops, which act as a deterrent to Russia.

But Austin was coy about committing more American Soldiers and Airmen to Romania when asked by a journalist if the investments would lead to additional troops.

“Our posture in the region continues to present a credible threat against Russia and it enables NATO forces to operate more effectively should deterrence fail,” he said, citing the ongoing force posture review. “No announcements to make today.”

In June, Romania hosted several hundred American troops as part of the Defender-Europe exercises, including missile defense exercises at Capu Midia. Romania’s 2 percent GDP spending on defense has helped the former communist dictatorship and Soviet ally emerge from behind the Iron Curtain and modernize its defense equipment with NATO interoperable hardware and American technology.

Romania hosts Phase 2 of NATO’s Ballistic Missile Defense system in Deveselu with the only operational Aegis Ashore system, active since 2016. Phase 3 will include an Aegis Ashore system in Redzikowo, Poland. Phase 1 of the missile defense program uses regional American naval assets with Aegis missile defense systems.

Preparing for the NATO Summit

Austin joined NATO Secretary General Jens Stoltenberg and defense ministers from the alliance Oct. 21 for two days of meetings that begin NATO’s strategic shift in the wake of the Afghanistan withdrawal.

While the American Defense Secretary was not scheduled to make public remarks until the meetings’ conclusion, Stoltenberg previewed the topics of discussion in a press conference Oct. 20, with a focus on NATO’s turn to technology.

“Future conflicts will be fought not just with bullets and bombs, but also with bytes and big data,” he said. “We see authoritarian regimes racing to develop new technologies, from artificial intelligence to autonomous systems.”

Stoltenberg said this week allies will kick off a $1.16 billion NATO Innovation Fund to develop dual-use emerging and disruptive technologies. NATO will also establish its first artificial intelligence strategy to incorporate data analysis, imagery, and cyber defense.

Stoltenberg also touched on historically low relations with Russia, which closed its mission to NATO this week and the NATO offices in Moscow following the expulsion of eight Russian intelligence officers from Brussels.

He also addressed the threat posed by Russia’s development of nuclear-capable and hypersonic missiles.

“These missiles pose a real threat to security in the Euro-Atlantic area,” he said. “We will not mirror Russia’s actions, but we will maintain strong deterrence and defense.”

In comments from Bucharest the same day, Austin predicted Afghanistan would be a topic of discussion.

“As you would imagine, no doubt, we will talk about NATO’s role post-Afghanistan and some of the lessons learned from Afghanistan,” Austin said.

Stoltenberg promised a “thorough and clear-eyed assessment” of the alliance’s 20-year involvement in the country, which began as a narrow counterterrorism mission and expanded to an “ambitious nation building effort.” Included will be an assessment of the risks of engaging in “big missions and operations outside NATO territory.”

Stoltenberg also expressed confidence that American commitment to NATO had returned after reluctance during the Trump era.

“What we see now is the U.S. administration which is strongly committed to rebuilding, strengthening alliances. And in particular strengthening the trans-Atlantic bond between Europe and North America,” he said.

Asked if NATO at its June 2022 summit in Madrid would give a strong signal to aspiring members, such as Georgia and Ukraine, where Austin visited prior to arriving in Brussels, Stoltenberg demurred.

“We will continue to work on how we can further strengthen the partnership with Georgia, how we can make sure that we both provide political and practical support,” he said.

Climate Change Likely to Lead to Instability, Increased Risks For Pentagon, Report Says

Oct. 21, 2021 | By Greg Hadley

Nearly nine months after President Joe Biden signed an executive order directing the Pentagon to incorporate the implications of climate change in its wargaming, analysis, and simulations, the Defense Department has released its Climate Risk Analysis report.

The report, out Oct. 21, “provides a starting point for a shared understanding of the mission risks of climate change—and lays out a path forward,” Defense Secretary Lloyd J. Austin III wrote in its preface.

It also comes two weeks after the DOD released its Climate Adaptation Plan, intended to guide decision-making as the department deals with the effects of climate change.

By contrast, the Climate Risk Analysis is primarily focused on identifying the different ways that a changing climate will likely challenge national security—both Biden and Austin have cited climate change as a major national security issue.

With higher temperatures, changing precipitation patterns, and more frequent, violent weather events, both first- and second-order effects are likely, the report noted.

“For example, the climate hazard of changing precipitation patterns is expected to cause more frequent and intense droughts in certain regions of the world. Primary impacts of drought include reduced water availability. Secondary impacts include reduced agricultural yields, which, in certain situations, could contribute to migration,” the report reads.

On top of those risks, “malign actors” could try to exploit instability caused by climate change for their own gain, the report added. Both internal and external tensions within certain countries could also be increased if there is competition for a scarcity of resources, leading to more security risks.

In the Indo-Pacific region in particular, key U.S. military installations are on islands that could be threatened by rising sea levels, and adversaries such as China could use the impacts to expand their influence.

While the report notes that “specific hazards, impacts, and risks associated with climate change will differ by region,” its sections on specific regions were deemed “Controlled Unclassified Information” and not included in the publicly released version.

The report does include a map showing the specific impacts of climate change and the resulting potential security implications by region. For U.S. Southern, European, and Africa Commands, the two main implications cited are increased requests for humanitarian aid and disaster relief and increased instability within and between countries.

For Central Command, the biggest potential risks will be increased instability and altered or limited environments for military operations. For Indo-Pacific Command, the potential security implications include disaster relief, limited environments for military operations, and increased demand for DOD support of civil authorities. The latter two are listed as implications for Northern Command, along with an added risk of increased need for transportation, communication, and monitoring in harsh environments such as the Arctic.

Department of Defense Climate Risk Analysis

“To keep the nation secure, we must tackle the existential threat of climate change. The unprecedented scale of wildfires, floods, droughts, typhoons, and other extreme weather events of recent months and years have damaged our installations and bases, constrained force readiness and operations, and contributed to instability around the world,” Austin wrote. “Climate change touches most of what this department does, and this threat will continue to have worsening implications for U.S. national security.”

The Pentagon’s report was one of four addressing climate change released by national security agencies Oct. 21—the Intelligence Community released a national intelligence issue on the topic predicting rising tensions and instability among nations as well—while the Department of Homeland Security released a Strategic Framework for Addressing Climate Change as well as a report on how the issue will affect migration.

Air Force Asks Boeing for E-7A Wedgetail Data for E-3 Sentry Replacement

Oct. 21, 2021 | By John A. Tirpak

The Air Force has taken the first step toward a rapid acquisition of Boeing’s E-7A Wedgetail airborne warning and control aircraft to replace the aging E-3 Sentry Airborne Warning and Control System, or AWACS, according to an Oct. 20 business opportunity announcement.

The Air Force announced it’s seeking information from Boeing to perform “studies, analyses, and activities required to ascertain the current E-7A baseline configuration and determine what additional work would be necessary” to make the aircraft compatible with Air Force “configuration standards and mandates.” It didn’t specify when it would be seeking the new airplane.

Senior Air Force leaders, at AFA’s Air, Space & Cyber conference in September, said they were looking favorably at replacing the E-3 with the Wedgetail, given its lower operating cost and non-developmental status. Air Combat Command chief Gen. Mark D. Kelly told reporters that to maintain “707-based” aircraft such as the E-3 is no longer feasible. Kelly said he anticipated no significant issues making the E-7 compatible with USAF needs, especially since it was designed and developed in the U.S.

The Air Force, alone among its allies, does not “field a cutting-edge, air-moving-target-indicator capability,” Kelly lamented. Commenting on the AWACS’ age and maintenance issues, he said, “There’s a reason why exactly zero airlines around the globe fly the 707. Because it takes a miracle … every day just to get it up in the air.”

The Air Force has operated the E-3 AWACS since 1977, and since then, NATO, the U.K., France, and Saudi Arabia have acquired their own examples. Japan operates a similar system hosted aboard the 767 airframe. The last E-3 was built in 1992. The aircraft is used to provide long-range detection, tracking, and identification of airborne threats, as well as command and control of friendly fighters, vectoring them toward intercepts of hostile aircraft.

Chief of Staff Gen. Charles Q. Brown Jr., speaking at ASC21, said the E-7 provides “an option to be able to get the capability much faster than if we were to start a new one from scratch.” He called the E-7 “a good platform” that he flew, or flew aboard, twice during his time as commander of Pacific Air Forces. Air Force Secretary Frank Kendall said the E-7 “could be useful” to shore up the AWACS mission.

The Wedgetail, which uses a fixed blade-like antenna on a 737 airframe—rather than a rotating radome like on the 707-based E-3 Sentry—was developed for the Royal Australian Air Force starting in 1999 and has operated with that service since 2009. It has also been selected by the U.K., Korea, and Turkey to equip their air services, offering interoperability advantages.

Gen. Kenneth S. Wislbach, current PACAF commander, noted that the Wedgetail is “a proven capability” and that he’s been impressed with its performance.

Brown suggested that funding for the E-7 could show up in the fiscal 2023 budget; the Air Force did not release out-year budget plans with its 2022 budget, now before Congress. The Air Force has used new rapid acquisition authorities given by Congress in the last few years to jump-start various prototyping efforts, as well as the F-15EX procurement.

The government wants to evaluate information regarding “diminishing manufacturing sources,” systems engineering, cybersecurity, airworthiness, test data, “spectrum allocation” and “future impacts of Federal Communications Commission forecasted sales of spectrums,” open mission systems, and M-code GPS. It designated Boeing as the only potential supplier of the system.

“The Aircraft Rapid Prototyping Requirements Document [RPRD] has specifically called out the E-7A and it has been determined that this is a sole-source requirement,” the government said.

The Air Force had planned to replace the E-3 with a “distributed” system, similar to what it is pursuing with the Advanced Battle Management System replacing the E-8 Joint STARS, but it has not said anything along those lines since it completed the Sentry Block 40/45 upgrade in 2020. Brown, however, said at AFA’s conference that the ultimate goal is to have a capability “that can be defensible” and suggested that a space-based system could be a solution.

None of the USAF leaders who addressed the E-7 said anything about how many the Air Force might buy, but the service fields 31 E-3 AWACS.

Kelly said a derivative of the Navy’s E-2D Hawkeye, which is a turboprop-powered aircraft with a rotating radome like that on the E-3 AWACS, would not match USAF’s needs.

There is some urgency to getting a Wedgetail acquisition underway, as Boeing is eyeing an end to 737 Next-Generation—on which the E-7 is based—in the 2025 timeframe, hence the “diminishing manufacturing sources” information request. The Wedgetail has much in common with the Navy’s P-8 Poseidon maritime patrol aircraft, also in use by several other countries. Boeing pitched a P-8/737-based JSTARS replacement in 2015, but the Air Force dropped that effort in favor of the ABMS.
