The US Air Force (USAF) had been planning to retire its B-1 and B-2 Stealth bombers in the early 2030s-time frame. Their retirement was expected because the B-21 was scheduled to enter service the next year. This next-generation stealth bomber, known as the “Raider”, is expected to be in service in large numbers by the end of the decade or into the 2030s at the latest. This originally would have left a gap of sorts in long-range strategic bomber capacity.
This level of drawdown in the bomber force is now being viewed as unwise because of the recent hostilities in Iran and the potential problems that could emerge in the Asia-Pacific theatre.
The Great US Air Force Bomber Upgrade
The USAF had planned to invest nearly $1.7 billion in continuing to modernize the B-1B Lancer and B-2 Spirit bombers over the next five years.
This itself was already a revision to earlier-stated plans to retire these bombers before the B-21 Raider is deployed with FOC across the service.
The funds that will now be expended to keep these older aircraft in service are being justified on the grounds that there will always be a need for assets available to conduct missions at long ranges and – in the case of the B-2 – into denied areas where stealth is a necessary aspect in order to maintain acceptable levels of survivability.
The USAF will need this fleet of at-the-ready long-range platforms while the “teething pains” of bringing the B-21 online restrict the availability of that type.
The other major strategic asset of the force, the B-52, will also experience availability issues while it undergoes one of the most ambitious modernization and overhaul upgrades in its history.
The improvements will include a new digital “J”-series configuration and an all-glass cockpit.
US Air Force Plans for B-1B Lancer and B-2 Spirit
Initial plans to mothball the B-1 and B-2s were shelved after both demonstrated their ability to contribute to major combat operations involving multiple platform types.

Additional funding secured by the Trump Administration for the defense budget then allowed the USAF to move forward with plans to upgrade both types.
The latest documentation on the USAF budget shows plans to spend $342 million on B-1 modernization from 2027 to 2031. “This request provides the necessary funding to modernize the platform, ensuring its lethality and relevance through 2037,” the budget document reads.
The B-2 is the even bigger winner in this process.
The 19-aircraft fleet will receive $1.35 billion in upgrades, installed in parallel with the B-1 modernization during this five-year “re-building” window.
Moreover, the budget documents show no scheduled retirement date for the B-2. Informed speculation is that the aircraft could still be flying into the 2050s.
Sensible Re-Investment
Retired Col. Mark Gunzinger, a former deputy undersecretary of defense and bomber expert who flew B-52s during his flying career, has been quoted as saying the B-2 is likely to remain in service longer and will still be flying as the B-1s are retired.

“Given the skyrocketing demand [for bomber capacity], it makes perfect sense to buy back the B-1 and B-2,” he said to the AFA’s Air & Space Forces Magazine.
“The B-2 is the only fully operational stealth bomber that we have, and frankly, long-range penetrating strike capability is one of the most significant shortfalls in our military. So why divest the B-2 early? It was completely budget-driven and resource-driven,” he continued.

In a separate statement, the USAF Global Strike Command said the B-2s will continue to operate from Whiteman Air Force Base, Missouri, as long as they are needed, including after the B-21s are in operational service.
The first operational B-21s will be fielded at Ellsworth Air Force Base, South Dakota, in 2027, with Whiteman later becoming the second base to host them.
“As we field the B-21, the requirement exists to simultaneously train and perform operational missions,” a Global Strike spokesperson said. “The B-2 will remain a critical long-range strike option for the President and will be maintained as a viable capability for as long as it is needed for national security.”
