"AFLCMC/EBD is seeking to award a Multiple Award Indefinite Delivery Indefinite Quantity (IDIQ) contract to support all aspects of research & development, production, testing, and delivery of the Next Generation Penetrator (NGP), GBU-76/B weapon system," the Air Force Life Cycle Management Center, Armament Directorate, Attack Division wrote in a contracting notice posted online.
GBU-76/B: the Next Generation Penetrator designated
The U.S. Air Force has publicly designated the Next Generation Penetrator (NGP) as GBU-76/B and has begun market research to identify industry partners able to support its full lifecycle. The contracting notice invites responses from "all interested vendors" to demonstrate capability across design, production, testing, and bed down of components and activities tied to developing, performing, and sustaining the GBU-76/B weapon system. The notice emphasizes that the current activity is for planning purposes.
Technical priorities named in the notice
The contracting notice lists a wide array of tasks that may be relevant to the effort. Explicit items include:
- fuze development and production;
- development and testing of the explosive filler;
- design and integration of an "Alternate Navigation System" to guide the bomb to its target;
- integration of all components into complete bombs;
- provision of mission planning and weaponeering software, and training assets and procedures; and
- logistics for movement and loading of the weapons into aircraft.
The notice also says the Air Force "will consider novel, demonstrated, or fielded Guidance, Navigation & Control (GNC) technologies with viability for integration into a warhead guidance system design that can achieve repeatable, high accuracy performance in GPS aided, degraded, and/or denied environments."
Fuzing, guidance and weight: design constraints and choices
Fuzing is highlighted as a critical element for deep-penetrating munitions. The notice and related reporting underline the need for fuzes that can "count" floors or sense voids to maximize damage after high-speed impact and subsequent penetration. The Air Force's prior descriptions of the program place the NGP's warhead in the neighborhood of 22,000 pounds, while the contracting notice asks vendors to show familiarity with lifecycle tasks for "Large Penetrator Warhead Systems weighing approximately 20,000 to 30,000 lbs." By comparison, the GBU-57/B MOP is a 30,000-pound-class bomb with a BLU-127/B warhead nominally weighing approximately 27,125 pounds.
The notice leaves open design variations: the Air Force has previously discussed the possibility of a powered design or an add-on rocket booster to extend reach or improve penetration characteristics. The GBU-76/B could therefore incorporate either passive or active mechanisms to enhance penetration or standoff employment.
Operational integration: B-2, B-21, testing and sustainment
Operational employment and integration are part of the planning exercise. The B-2 is currently the only aircraft certified to employ the GBU-57/B operationally and can carry two MOPs at a time; the B-21 is smaller and is expected to carry a single MOP at a time. The Air Force has noted that making the GBU-76/B lighter or smaller than the MOP could aid future integration on the B-21. The service also already maintains specialized training and handling equipment for the MOP—including a full-size mock B-2 bomb bay and trolleys for moving inert weapons—and the notice asks vendors to support associated mission planning and logistics.
The Air Force's Fiscal Year 2027 budget request sets a schedule for prototyping: "Next Generation Penetrator Prototype Demonstration including Modeling and Simulation, Design, Product Development, and Test" is slated to wrap up at the end of Fiscal Year 2028. The notice also notes that MOP funding has supported construction of a new test target referred to as MS-34, underscoring continued emphasis on live testing alongside virtual weaponeering.
What this means for Applied Research Associates, Boeing, and Air Force planners
- Applied Research Associates, Inc. (ARA): ARA already announced in September 2025 that it received a contract for NGP work to include production and delivery of full-scale prototypes—placing it squarely among early movers in prototype delivery.
- Boeing: The notice and program reporting indicate Boeing will "drive tail kit development and support all-up-round integration" on NGP work, building on its role as prime contractor on the MOP.
- Air Force planners: The service is balancing near-term upgrades to the GBU-57/B—work on tail kit and fuze improvements and efforts to replenish or expand stockpiles following Operation Midnight Hammer—with longer-term prototyping and potential acquisition of GBU-76/B systems. Fielding timelines remain unclear even as prototyping activity is scheduled through FY2028.
The GBU-76/B designation marks a formal step in replacing the GBU-57/B, but it does not signal an immediate retirement of the existing weapon. The Air Force intends to continue upgrading and sustaining the MOP while it pursues the GBU-76/B, and the contracting notice confirms that the service is still collecting information to refine requirements across guidance, fuzing, warhead design, and logistics. The next tangible milestones will be prototype demonstrations through FY2028 and continued vendor responses to the IDIQ planning effort.
