The up-and-coming Northrop Grumman B-21 Raider 6th-generation stealth bomber is not a supersonic warplane; ditto for (1) its immediate predecessor, the pre-merger Northrop B-2 Spirit (the original stealth bomber), and (2) the septuagenarian B-52 “Stratosaurus” (unofficially AKA the “Stratosaurus”).
Indeed, the only member of the US Air Force’s strategic bomber triumvirate that flies in excess of Mach 1 is the B-1B Lancer (aka “the Bone“).

However, though the Raider isn’t a “Mach buster,” that’s not stopping its production efforts from proceeding at breakneck speed (well, breakneck speed by Pentagon acquisition standards, anyway).
Just a few days ago, we reported that Northrop Grumman and the USAF were accelerating production capacity of the B-21.
And now there’s talk of literally doubling down on that by establishing a second B-21 production line.
B-21 Raider Buildup Bottom Line Up Front (BLUF): Doubling Down?
Two key sources for this story are (1) a March 18, 2026, staff report by Exchange Monitor and (2) an article by Stephen Losey of Air and Space Forces Magazine published that same day.
Both of these reports center on testimony delivered on March 17 by Adm. Richard Correll, head of US Strategic Command (STRATCOM), to the House Armed Services Committee’s (HASC) strategic forces panel. In those remarks, Adm. Correll told the Congressional panelists that (1) STRATCOM still believes the Air Force needs to increase its planned B-21 fleet to 145 airplanes—a figure that his predecessor, now-retired USAF Gen. Anthony J. Cotton, endorsed last March, and (2) a second production line could be a way to reach that goal.
In the Admiral’s Own Words
“There’s ongoing work within the Joint Force to determine what that end point might be, and there are, of course, investments that have been made to increase the production rate and potentially to open a second production line–that decision has yet to be made.”

A B-21 Raider conducts flight tests, which includes ground testing, taxiing, and flying operations, at Edwards Air Force Base, California, where it continues to make progress toward becoming the backbone of the U.S. Air Force bomber fleet. The B-21 will possess the range, access, and payload to penetrate the most highly-contested threat environments and hold any target around the globe at risk. The B-21 program is on track to deliver aircraft in the mid-2020s to Ellsworth Air Force Base, South Dakota, which will be the first B-21 main operating base and location for the B-21 formal training unit.

The B-21 Raider is designed with an open systems architecture, enabling rapid insertion of mature technologies and allowing the aircraft to be effective as threats evolve. The bomber was designed up front for supportability and maintainability-based upon decades of lessons learned and best practices from prior aircraft programs-to improve long-term affordability and outcomes in operations and sustainment. The B-21 first flight is anticipated to take place in calendar year 2023. (U.S. Air Force photo)

That particular sentence was uttered in response to a question from Rep. Don “Bits” Bacon (R-Neb.; himself a retired USAF brigadier general), who said “we’re hearing now that maybe 150 B-21 bombers is the target area” by the Defense Department, and whether “we’re building the infrastructure to support that.”
Adm. Correll added that “Clearly, the B-21 represents a really significant capability from a conventional and a nuclear perspective for the Joint Force–a sixth-generation stealth capability with stand-in or stand-off precision strike and the ability to maneuver within a contested electromagnetic spectrum, so what it [the B-21] enables for the Joint Force goes beyond the strike capability associated with it.”
Bombers by the Numbers
Thus far, the USAF (other than Gen. Cotton) has been somewhat minimalistic (for lack of a better word) in its public statements on desired B-21 production numbers, simply stating its Raider production target is “at least 100 aircraft.”
Ergo, 145 airframes would represent a 45 percent increase over that baseline.
According to the World Directory of Modern Military Aircraft (WDMMA), the US Air Force currently has 19 B-2s, 45 B-1s, and 76 B-52s, for a total of 140 bombers.
Therefore, 145 B-21s would equate to a 1.03-1.00 matching ratio.
“Teamwork Makes the Dream Work”
The B-21 is strictly an Air Force asset (ditto for the aforementioned trio of currently serving strategic bombers), yet that doesn’t stop a proud Navy man like Adm. Rich Correll from advocating for it.
This stands out as a refreshing contrast to the political turf battles—”parochialism,” as the late, great Senator (R-AZ) and Air Force Reserve Maj. Gen. Barry Goldwater termed it (as cited by Hedrick Smith in his Pulitzer Prize-winning 1987 book “The Power Game: How Washington Works“), an all-too-often afflicting the sister services’ competition for funding (far more acrimonious than the comparatively friendly interservice rivalries played out on the college football gridiron).
In his position as the multi-service unified combatant command, STRATCOM, Adm. Correll is instead putting aside those rivalries for the sake of “One Team, One Fight.” Bully for you, Admiral!
