An agreement to ramp up production of the B-21 Raider was indeed structured to at least open the door to orders for more of the bombers, according to prime contractor Northrop Grumman. When the deal was announced back in February, the U.S. Air Force described it as a tool primarily intended to simply help accelerate fielding of the B-21. The service also said that long-stated plans for a fleet of 100 aircraft remained unchanged. Since then, it has separately confirmed that it is reassessing the objective Raider fleet size.

Northrop Grumman CEO Kathy Warden was asked about the prospect of orders for more than 100 B-21s during a quarterly earnings call earlier this week.

“The agreement we reached with the Air Force does allow them to consider accelerating production into a larger program of record, and we are working with them in that analysis,” Warden said. “They are undertaking it now. I expect that by year-end they will come to a conclusion on that, and we’ll certainly keep you updated.”

The deal, as it was announced earlier this year, centers on a 25 percent boost in annual B-21 production capacity. Raider production rate details have been and remain classified, but past reports have said that Northrop Grumman is understood to be able to churn out up to eight of the bombers a year.

As noted, emphasis was placed at the time on production acceleration to support fielding of the first operational B-21s next year. Any possibility of a larger total fleet size was downplayed.

U.S. officials have increasingly voiced support for a fleet of more than 100 B-21s for years now. Just in April, Secretary Pete Hegseth told members of the Senate Armed Services Committee that he saw a need for “a lot more” B-21s. However, the Air Force has repeatedly said there has been no change in the official acquisition plan.

The first sign of actual change being on the horizon came in May. That month, Air Force Lt. Gen. David Tabor, Deputy Chief of Staff for Plans and Programs, made clear that the planned Raider fleet size, or so-called program of record, was at least under formal review at a hearing before the House Armed Services Committee.

“We’re in the process of sharpening our pencils, really getting down to exactly what that [revised program of record] is,” Tabor said at that time, according to Air & Space Forces Magazine. “I think here in the next year, by the time we get to the ’28 [Fiscal Year 2028] budget, we’ll be able to give you a better answer, much more precise answer, and show you our homework.”

The Pentagon’s annual proposed budget for the upcoming fiscal year is typically released sometime in the spring. During the earnings call this week, Northrop Grumman CEO Warden indicated that the final decision on a new B-21 fleet size target is actually expected to come months before then, which makes sense in the context of the lengthy budget planning process.

What that new B-21 fleet number might be remains to be seen, and it is not clear whether it will even be publicly disclosed. In February, an Air Force official told TWZ that any revised figure is expected to be classified. Cost, schedule, and other details about the Raider program continue to be shrouded in heavy secrecy even as the aircraft has moved into increasingly public testing ahead of its planned fielding next year.

In terms of overall progress, the Air Force and members of Congress have repeatedly described the B-21 as a model acquisition effort that has been able to stay within cost and schedule targets despite at least a few hurdles during development.

On “B-21, there’s been good execution throughout the years,” John Greene, Northrop Grumman’s CFO, also said on the earnings call this week. “So, that’s been an enabler to ensure the overall program profitability remains on a direction that’s headed north.”

Air Force officials have also been open about their excitement for what the B-21 will bring operationally, as well as the added capacity that will come from having even 100 of these bombers. The B-21 is notably smaller than the B-2, but it will offer extreme range and other substantially improved capabilities compared to its predecessor. There are also only 19 B-2s still in service, and those aircraft, though highly capable, are very much a ‘silver bullet’ force.

B-21 Takeoff and Landing

The Raiders will replace the Air Force’s aging B-1B swing-wing bombers, as well. There is no clear replacement plan for the B-52 bomber yet, with those aircraft set to continue flying through at least 2050. To ensure their relevance for decades to come, the B-52s are in the process of receiving an extensive array of upgrades, including new engines and radars, but there have been delays. How those efforts continue to unfold might also have implications for the B-21 even though the two aircraft fill very different roles.

By all indications, the B-21 remains on track to begin fielding next year. The Air Force just recently made an announcement about the operational crew complement for the bombers, which will be two pilots. You can read more about this decision and its significance here.

It will still be some time before the B-21 force reaches a true operational capability even after initial fielding begins. Raider deliveries are also set to continue for years, especially if the total planned fleet rises well above 100 aircraft.

Boeing has provided details of the latest iteration of its MQ-28 Ghost Bat collaborative combat aircraft (CCA). Already, the Ghost Bat was the most mature known CCA, but the enhanced version of the drone, the Block 3, has various new features. These include a larger wing and a pair of internal weapons bays, which means it can carry munitions without diminishing its low-observable characteristics.

The MQ-28 Block 3 was revealed today at the ILA Berlin airshow, taking place this week in the German capital. The unveiling was conducted by officials from both Boeing Australia and Germany’s Rheinmetall. The German firm is partnered with Boeing to offer the drone to the German military, as well as to tap into the potentially very lucrative European CCA market.

“This is the aircraft that we are offering to Germany,” MQ-28 Global Program Director, Glen Ferguson, said at the rollout. “This is the third iteration of design now, and we are on point to build out first [Block 3] aircraft next year.”

The previous Block 1 and Block 2 variants have completed more than 150 test sorties in Australia and the United States.

Australia has already acquired eight Block 1 MQ-28s, which are configured as pre-production prototypes.

The first nine Block 2 drones, now in production, are seen as a pathway to an operational capability, which is fully realized in the Block 3.

The Block 3 aircraft features a wing that is 25 percent larger, combined with a thrust increase from 10,000 pounds to 12,000 pounds. It’s not immediately clear how that thrust increase will be achieved, but coupled with greater wing area, it will confer an increased payload capability. This translates into an additional 2,000 pounds of fuel, stores, and mission payloads.

“That additional capacity gives operators freedom to balance payload and endurance to configure for the mission at hand, whether that means carrying extra fuel for longer-range operations, increasing weapons carriage, or any combination of both,” Ferguson said.

The latest iteration of the drone also adds beyond-line-of-sight (BLOS) control. Introduction of BLOS communication links means the MQ-28 can be operated at unlimited standoff distances, whether from a ground station, a naval vessel, or a crewed aircraft. With its range of over 2,000 nautical miles, adding BLOS to the drone also ensures that it can conduct independent operations when not controlled by a crewed aircraft, which was always envisioned as a potential role for Ghost Bat. Having a SATCOM option also opens up better resiliency for control in electronic warfare combat environments.

“Inclusion of features such as BLOS capability is a direct result of our learnings to date along with feedback from air forces as they understand more about the role and integration of CCAs into joint force operations,” Ferguson explained.

As for the critical internal weapons bays, these are added within each side of the slab-side fuselage, shown in a video released by Boeing.

Each bay can carry a single AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) or two Small Diameter Bomb (SDB) precision-guided munitions. These can comprise either the GBU-39/B SDB I or the GBU-53 SDB II, also known as StormBreaker. The Ghost Bat is the first CCA we have seen capable of carrying AIM-120s internally, a significant development in itself. The option for internal stores carriage is also a huge deal at this point, with Boeing having recently validated its radar cross-section (RCS), proving that the CCA is harder to detect and better able to operate in contested environments.

“The combination of a highly capable platform, stealth features and advanced autonomy provides unprecedented ability for air forces to extend their mission effectiveness and operational flexibility,” said Brad Thompson, director for Phantom Works Australia, after the completion of the RCS trials.

The drone also has provision for three external weapons stations. At least one of these has already been tested, during an end-to-end engagement in which a target drone was brought down by an AMRAAM. The air-to-air role is notably relevant since the drone is also envisaged as a force-protection asset, to defend airborne early warning aircraft and tankers, etc, as well as working with fighter aircraft. Combined with more thrust and larger wings, the external pylons would appear to open up the possibility of flying with as many as five AMRAAMs, and at least four, or with a mixed load of air-to-air and air-to-ground weapons.

For Block 3, Boeing is also known to be working on three or four alternative sensor payloads. Integration of these would be facilitated by the fact that the entire nose can be swapped out to accommodate different payloads.

Bringing the MQ-28 Block 3 from Australia to Berlin reflects the relationship between Boeing Australia and Rheinmetall and the fact that the German Air Force — the Luftwaffe — is being pitched to for its CCA requirement.

“At the moment, we are still in negotiations with the German government, but if they want to have the plane by 2029, my expectation is that by at least next year, we have to go into the final stage of negotiating the contract,” Rheinmetall CEO Armin Papperger told Breaking Defense.

In expectation of a German CCA requirement, the ILA Berlin airshow featured a heavy presence of combat drones.

Also making its public debut was a full-scale model of the Airbus U760 Ravenstorm, a combat drone designed to operate alongside fighter aircraft in air-to-air combat, strike missions, and electronic warfare roles. The new uncrewed aircraft is part of a revamped drone portfolio from the company, and you can read more about it here.

As well as Ravenstorm, Airbus is also offering a Europeanized version of the stealthy XQ-58A Valkyrie, which is apparently being pitched as a lower-cost aircraft and one that offers the option of runway-independent operations.

From the United States, General Atomics Aeronautical Systems presented a full-size model of a drone from its Gambit family, with the company also confirming that it has been in talks with Germany regarding its CCA requirements.

Meanwhile, German firm Helsing revealed a new version of its CA-1 Europa drone — which looks remarkably similar to Ghost Bat. The CA-1EA (for Electronic Attack) follows the CA-1KA (Kinetic Attack) and reflects the high priority Germany attaches to its need for a CCA to accompany its forthcoming Eurofighter EK electronic warfare jets, as well as other combat aircraft.
