Defense firm Applied Research Associates will design and build a prototype for the Air Force's Next Generation Penetrator bomb, the company and the service announced over the weekend.

The new contract -- which spans 24 months and includes the production and test of sub-scale and full-scale prototype munitions -- was awarded by the Air Force Life Cycle Management Center’s Eglin Munitions Directorate.

ARA will serve as the lead designer for the development of a bunker-buster, air-to-ground munition prototype, while Boeing will build the NGP’s tail kit.

“This effort will evaluate capabilities against hard and deeply buried targets that pose critical challenges to U.S. national security,” ARA wrote in its news release. “Leveraging decades of experience in guided and penetrating munitions, ARA will lead design maturation, while Boeing will drive tail kit development and support all-up-round integration.”

Boeing is the manufacturer of the Air Force’s other munition intended to destroy hard-to-hit and deeply buried targets, called the GBU-57 Massive Ordnance Penetrator. That weapon was used for the first time in June to strike Iran’s nuclear enrichment facilities.

NGP is a follow-on, secretive program the Air Force introduced in fiscal year 2025 to develop an advanced munition weighing no more than 22,000 lbs. able to be carried by various aircraft.

The project potentially includes the addition of advanced fuze technology to the penetrating weapon system to better ensure it can reach a precise aim point even when other satellite navigation systems go offline, the service wrote in its FY-25 budget request documents.

The service has also floated the idea of adding a rocket motor to the next bunker-buster iteration to increase its standoff capability. The MOP, in contrast, is unpowered, meaning it needs to be released close to the target.

In FY-26, the service is requesting $73.7 million for NGP research, development, test and evaluation to “execute varied validation activities to include: modeling and simulation, test and evaluation, ground test support for sub-scale sled testing and full-scale static testing.”

ARA will likely be required to deliver about “10 subscale and 3-5 full-scale warheads 18-24 months from contract award,” according to a February 2024 request for information.

Prototype demonstration for the NGP program is planned to be complete by the end of FY-27, per Air Force budget documents.

President Trump today signed an executive order authorizing the use of "Department of War" as a secondary title for the Defense Department.

Some GOP lawmakers are pushing to codify the name change into law as only Congress can rename federal agencies, but Trump today authorized the use of “secretary of war” and “Department of War” for public communication.

Defense Secretary Pete Hegseth has also updated his social media handle on X to be @SecWar following a signing ceremony in the Oval Office. The department’s official X account was also updated.

“WE ARE THE WAR DEPARTMENT,” the account declared.

The Pentagon’s official website www.defense.gov has also been changed to www.war.gov.

Hegseth, speaking alongside Trump in the Oval Office, said the name changes reflect the administration’s priorities.

“We're going to go on offense not just on defense,” he said. “Maximum lethality -- not tepid legality. Violent effect, not politically correct. We're going to raise up warriors. Not just defenders. This War Department, Mr. President, just like America, is back.”

Trump said “Defense Department” -- which remains the department's legal name -- is too “politically correct” and “wokey.”

“It has to do with winning,” he said. “We should have won every war. We could have won every war. We really chose to be a very politically correct or wokey and we just fight forever.”

Senate Appropriations defense subcommittee Chairman Mitch McConnell (R-KY) responded on X, criticizing the size of the Trump administration’s fiscal year 2026 defense spending request.

“If we call it the Dept. of War, we'd better equip the military to actually prevent and win wars,” he wrote. “Can't preserve American primacy if we're unwilling to spend substantially more on our military than Carter or Biden. ‘Peace through strength’ requires investment, not just rebranding.”

The U.S. Department of War was created in 1789, reorganized in 1947 as the National Military Establishment and then renamed the Department of Defense in 1949.

The Air Force Research Lab is gauging private-sector interest in developing reliable and precise position, navigation and timing (PNT) technology to coordinate swarms of small drones in GPS-denied or degraded environments with harsh physical conditions, per a request for information published yesterday.

Input on such capabilities from industry is due Sept. 19.

The Air Force Research Laboratory isn’t yet soliciting prototype proposals, but its air domain research unit is gauging industry interest in supporting a VPX ruggedized testbed for position, navigation and timing prototypes that incorporate its Next Generation Atomic Clock -- a low-power, advanced system designed to maintain precise time measurement and synchronization.

Such a testbed would use a decentralized but standard open PNT architecture so platforms can operate without GPS. It would also allow swarms of small drones to establish reference frames using measurements between the platforms, so they can start navigating together without prior positioning data. As the swarm continues to operate, the positioning accuracy will improve with the accumulation of real-time data.

The VPX ruggedization means this testbed would also allow for the integration between platforms and the assessment of prototypes’ operation in harsh physical environments.

“This system is critical for maintaining coordinated flight, accurate data collection, advanced sensor fusion, and effective mission execution,” the notice said.

It comes as PNT capabilities continue to gain traction as a high-priority mission requirement for the Defense Department. The Pentagon’s science and technology chief brought it up last week at the National Defense Industrial Association’s annual emerging technology conference.

“If I were to say we need to be able to operate through highly contested environments with a given mission, well, one of those important aspects is assured position, navigation and timing,” said Michael Holthe, performing the duties of assistant defense secretary for science and technology.

The RFI also comes more than a year after a Defense Science Board task force recommended the Pentagon attempt to leverage commercial markets for the rapid scaling of PNT systems for military use.

The Navy has awarded a cumulative $10 billion to 59 different contractors to provide various forms of logistics support, supplies and services for geographic combatant commands, coalition partners and U.S. federal agencies, according to a Sept. 4 contract announcement.

The base period will begin in October and is expected to conclude in December 2029. The awards could be worth as much as $20 billion with work stretching to December 2034 if a five-year extension option is exercised.

The awards fall under Naval Supply Systems Command’s “Worldwide Expeditionary Multiple Award Contract (WEXMAC)” initiative, launched in 2021 as a means of providing faster and more flexible contracting support to expeditionary forces by pre-selecting a group of companies to eliminate the need for repetitive ad-hoc contract requests.

This batch of WEXMAC awards are “Territorial Integrity of the U.S. (TITUS)” contracts, with the companies tapped to provide services and supplies including “humanitarian assistance/disaster relief, contingency, exercise, lodging, logistics, water-based and land-based support,” the announcement states.

The contracts were competitively awarded, with the Navy receiving a total of 109 offers. In addition to the 59 companies covered under this award, the Navy received 37 offers from incumbent contractors from prior WEXMAC awards that were found compliant and will receive modifications to their existing contracts, the notice states.

The Senate Armed Services Committee is scheduled to convene on Sept. 11 to hold a nomination hearing for Marine Corps Gen. Christopher Mahoney, who has been tapped to serve as vice chairman of the Joint Chiefs of Staff.

If confirmed, Mahoney, who currently serves as assistant Marine Corps commandant, would succeed Adm. Christopher Grady.

As vice chairman, Mahoney would co-chair the Joint Requirements Oversight Council, which -- for now -- governs the process for validating and prioritizing what the military needs.

The job is set to be transformed, however, as the Pentagon recently announced the disestablishment of the Joint Capabilities Integration and Development System.

If confirmed, Mahoney would co-chair a new Requirements and Resourcing Alignment Board (RRAB) that is slated to be stood up over the next 120 days and is intended to link military requirements to the Pentagon budget process, choose “Key Operational Problems” (KOPs), and decide which will be resourced. The RRAB will also have the power to recommend canceling or redirecting service-specific programs.

Meanwhile, under the new regime the JROC will no longer validate service-level requirements, except when required by law. Instead, the JROC will focus on ranking the new KOPs representing the biggest warfighting gaps tied to the National Defense Strategy and the Joint Warfighting Concept.

Last week, Grady, noting the dissolution of JCIDS, said DOD is moving with haste toward its latest round of acquisition reforms.

“There is good momentum in the building to get after that,” he said. “JCIDS was in significant need of reform. The answer was: Let’s just get rid of it and think of different ways to do the business.”

Austal USA has entered into a strategic outsourcing agreement with fellow Alabama-based shipbuilder Master Boat Builders that will see the two companies collaborate on current programs in Austal’s portfolio as well as undisclosed future efforts, Austal announced today.

Under the agreement, Master Boat Builders will support Austal on “select programs” including the Landing Craft Utility 1700 series (LCU-1700) for the Navy, an Austal spokesperson told Inside Defense. Austal is on contract for five LCUs -- designed to carry vehicles and heavy cargo from ship to shore -- with options for up to seven additional vessels.

According to the announcement, “pilot projects” will be identified in the coming months, followed by a phased implementation approach. The partnership is intended to expand shipbuilding capacity by enabling regional shipyards to take on complex government programs.

“By distributing work across complementary facilities, Austal USA and Master Boat aim to reduce bottlenecks, shorten production schedules and create surge capacity for future demand. The companies also intend to co-invest in workforce development initiatives,” the announcement states.

Strategic outsourcing is one approach shipbuilders are pursuing to accelerate production across the Navy’s portfolio. Shipbuilding giant HII has made the practice a key piece of its plan to expand production capacity, and Austal itself is building Virginia- and Columbia-class submarine modules in an outsourcing arrangement with General Dynamics Electric Boat.

Austal is building a new, $450 million fabrication facility to expand submarine module work and is a limited partner in the United Submarine Alliance (USA) Qualified Opportunity Fund -- a shipbuilding venture managed by private equity that may eventually provide additional space and infrastructure to further expand Austal’s module work.

Austal also builds a range of naval surface ships, launching a steel production line in 2022 and taking on several new programs in recent years as serial production of its aluminum Independence-class Littoral Combat Ships reached its conclusion.

The company’s current portfolio includes Navajo-class Towing, Salvage and Rescue ships (T-ATS), Bethesda-class Expeditionary Medical Ships (EMS), TAGOS-25 Ocean Surveillance Ships and the Coast Guard’s Heritage-class Offshore Patrol Cutter.

Master Boat Builders, located in coastal Alabama relatively near to Austal’s Mobile yard, builds commercial ships including offshore supply vessels, tugboats, fishing boats and dive support vessels for domestic and international customers. The family-owned company was established in 1979 and currently has about 300 employees.

The Army wants to see how well its Infantry Squad Vehicles handle without a driver after giving out contracts to three companies.

Forterra, Overland AI and Scout AI will pair their own self-driving solutions with Army ISVs and run through tests next May under three awards adding up to $15.5 million, an Army announcement revealed last week.

“We are looking forward to seeing how our industry partner’s autonomy solutions perform on vehicles while performing relevant military missions,” Col. Ken Bernier, project manager of the Future Battle Platforms project office, said in a statement. “We remain committed to bringing the best technologies to our warfighters and shaping the future of autonomous mobility for our Army at an unprecedented speed.”

The testing initiative, coined the “UxS Autonomous Maneuver Program,” will also involve a six-month stint with an Army unit under the service’s transforming in contact initiative, according to an Overland announcement for the award.

The program in total will run over a 16-month period and the Army could end up buying as much as $150 million worth of units, a Scout AI release says.

Overland uses an off-roading autonomy stack called OverDrive, which the Pentagon has already put to the test with the Defense Advanced Research Projects Agency’s Robotic Autonomy in Complex Environments with Resiliency (RACER) program.

Forterra will fit four ISVs with its own autonomy stack, called AutoDrive, the company announced in a press release yesterday, and Scout will integrate its autonomy stack, known as Fury, with the help of Textron Systems.

That comes after Army Secretary Dan Driscoll in recent months has touted the importance of harnessing commercial innovation to deliver soldiers capability fast, citing an example of how Silicon Valley company Applied Intuition in June morphed an ISV into a self-driving car in just 10 days.

“This award demonstrates the Army’s intent to leapfrog legacy automation systems and incorporate AI,” Colby Adcock, co-founder and CEO of Scout, said in a statement.

The Survivable Airborne Operations Center began flight testing last month, prime contractor SNC announced today.

The company, also called Sierra Nevada Corp., conducted its first flight of the aircraft Aug. 7 and will continue testing as part of its engineering and manufacturing development contract, according to a news release.

The Air Force awarded SNC a $13 billion contract for the aircraft in April 2024.

SNC currently has four Boeing 747-8I jets at its Dayton, OH facility which will be modified to become the E-4C, according to the company.

“Flight and ground testing will continue into 2026 to establish the technical design baseline,” the news release states. “Activities will primarily occur in Dayton, Ohio and Wichita, Kansas. Accomplishing these test activities early in the developmental program was a distinguishing aspect of SNC’s innovative approach to manage risk and avoid problems from arising later in the schedule.”

SAOC is set to replace the E-4B National Airborne Operations Center as part of the Nuclear Command, Control and Communications modernization effort in the Air Force. NAOC was built in the 1970s and is reaching the end of its life, the service has said.

According to SNC, the program has so far met all milestones on schedule.

The Army has awarded Lockheed Martin a $9.8 billion multiyear contract for the Patriot Advanced Capability-3 Missile Segment Enhancement system, the service's Program Executive Office for Missiles and Space announced today.

The contract runs through fiscal year 2026 and includes the procurement of 1,970 missiles “and associated hardware for U.S. and international partners,” according to an Army news release.

PAC-3 MSE, designed to counter tactical ballistic and cruise missiles as well as hypersonic threats and aircraft, is among the weapon systems Congress has granted the Pentagon multiyear procurement authorities for in recent years.

Maj. Gen. Frank Lozano, who leads PEO Missiles & Space, said in a statement Wednesday that multiyear contracts such as this one “mutually benefit both the government and our industry partners.”

“Our procurements at PEO Missiles and Space are beneficial because they enable the Army to procure a larger quantity of missiles for more rapid delivery, thus filling our inventory faster,” he said.

The multiyear award will allow the Army to both “achieve cost predictability and savings while strengthening the critical munitions supply chain and maximizing our operational efficiency,” Joseph Giunta Jr., senior contracting official for Army Contracting Command, added.

The Army awarded a three-year, un-definitized multibillion-dollar contract to Lockheed in June 2024 for the purchase of up to 870 PAC-3 MSE interceptors, Inside Defense reported at the time. Lockheed said Wednesday that contract is now “definitized,” meaning that it is included in the $9.8 billion contract awarded today.

Prior to the contract award, Lockheed was already in the process of increasing its annual production of PAC-3 MSE to 650 per year, the company said Wednesday.

Two Army officials who were scheduled to speak at an annual conference hosted by Defense News Wednesday morning canceled their appearance at the last minute following a directive from higher up within the Defense Department.

Brandon Pugh, the principal cyber adviser to the Army secretary, and Lt. Gen. Karl Gingrich, the deputy chief of staff of the Army G-8, were among multiple defense officials scheduled to speak Wednesday at the conference in Washington. However, it was announced at the conference that they canceled their appearance the day before.

According to a statement from the Army Communications and Outreach Office provided to Inside Defense, “attendance of Army senior officials to speak at the Defense News Conference was disapproved by the Office of the Assistant to the Secretary of Defense for Public Affairs.”

Additionally, Rep. Rob Wittman (R-VA) was scheduled to speak at Wednesday’s conference, but canceled his appearance and instead recorded a five-minute video.

The Defense News conference is the latest in a series of public events in which defense officials from the Trump administration have canceled their previously scheduled appearances on short notice.

In July after several officials pulled out of their planned appearance at the Aspen Security Forum, the Defense Department announced it was reviewing its participation in all think-tank events to ensure that the host organizations aligned with the politics of the Trump administration. However, that policy has since extended to other organizations that are not think tanks.
