The U.S. Navy’s Stealth Bomber That Died in 1991: The A-12 Avenger II
Summary and Key Points: A carrier-launched stealth bomber would have transformed carrier air wings by expanding strike options and compressing adversary reaction time. The Navy tried to build exactly that with the A-12 Avenger II, launched under the Advanced Tactical Aircraft program in the early 1980s to replace the A-6 Intruder.
Built around stealth shaping and carrier suitability, the program showed promise but ran into major weight, cost, and schedule problems.
Cancelled in 1991, the A-12’s ambition didn’t vanish—it echoed into later unmanned breakthroughs like the X-47B carrier demonstrations and today’s MQ-25 Stingray.
In 2 Words: Carrier Bomber — The A-12 Avenger II and the Road to Drones
It’s easy to envision the incredible tactical benefit that a carrier-launched stealth bomber would provide to a Carrier Air Wing by projecting new dimensions of air power and holding adversaries at risk in unprecedented ways.
US carriers have not offered such a capability, yet it was possible years ago.
A carrier-launched bomber was developed using Air Force stealth technology in combination with Navy weapons developers to bring a new kind of firepower to maritime war.
Development of the A-12 Avenger program began in the early 80s as the Advanced Tactical Aircraft (ATA) program.
The original intent was to replace the Northrop Grumman A-6 Intruder, then in service with the United States Navy and the US Marine Corps.
The proposed aircraft, engineered by McDonnell Douglas and General Dynamics, was ultimately canceled in 1991 due to reported delays, cost overruns, and other industry-Navy complexities.
As far back as the 1980s, the US Navy had been developing this A-12 Avenger II, a stealthy carrier-launched first-of-its-kind platform.
The Navy developed the platform to launch from and land on a carrier and to perform bombing missions.
The Navy built prototype demonstrators and conducted tests, and the project at times showed promise.
Boeing and General Dynamics won a deal to develop the aircraft in 1988.
A-12 Cancelled
However, in 1991, the project was canceled by the Pentagon and former Vice President Dick Cheney due to cost overruns, weight challenges, and other technological complications, according to an article in The National Interest.
The A-12 Avenger II was initially designed to replace Northrop’s A-6.

However, the project was abandoned in favor of the F/A-18 Hornet.
Why would this amazing breakthrough technology possibility be canceled?
Indeed, a stealthy bomber would have been and still is an extraordinary value-added addition to a Carrier Air Wing.
Such an airplane would bring new tactics, attack possibilities, and concepts of operation to the US Navy aircraft carrier power projection.
A-12 Technological Challenges
Looking back a few years, the A-12 Avenger II was most likely canceled for technological reasons, given the complexity of the engineering challenges involved.
However, the concept and ambition certainly lived on, and the US Navy is now engineering specialized new unmanned systems and command-and-control centers to support drone operations from carriers.
Many news essays about the Avenger II at the time of its cancellation spoke of soaring costs and design complications.
However, the Navy has moved on to introduce new platforms beyond the F/A-18 Super Hornet and Growler. And that means a move towards drone platforms. Clearly, the Navy keeps innovating, even if the idea of a stealth bomber did not work out.
The longstanding vision of accomplishing what seems impossible is likely why the successful take-off and landing of the X-47B were so monumental.
While the A-12 Avenger effort may have been regarded as a failure, it may have informed new stealth designs now supporting the US Navy. While this is clearly not a bomber, history was made.
X-47B Stealthy and MQ-25 Drones Takes Flight
The United States Navy made history roughly ten years ago by launching the stealthy X-47B demonstrator drone from the deck of an aircraft carrier, a long-sought-after technological capability intended to usher in a new era of carrier air attack.
At the time, Navy weapons developers explained the long-term, massive development effort that made this possible, which involved creating complex new algorithms, navigational technologies, and command-and-control systems.

This was considered a breakthrough achievement at the time.
US Navy weapons developers described attempting to land a drone on an aircraft carrier as presenting entirely new challenges compared to historic manned carrier flight.
In particular, Navy developers explained that a new generation of technologies was needed to enable an unmanned system to navigate changing sea states and wind conditions, as well as the challenges posed by landing on a “moving” carrier.
It is not clear what happened to Northrop’s X-47B after its successful flight, but in subsequent years, the service has developed a first-of-its-kind unmanned aerial refueler called the MQ-25 Stingray.
This platform, which brings carrier-launched unmanned technology to refuel from a carrier air wing, is now successfully arriving after years of development.
Many consider the X-47B and MQ-25 breakthrough developments because of the many years the US Navy had been attempting unmanned carrier flight.

I read your article with interest. I was a contracting officer on a similarly sized USAF program at the same time of the A12’s development. A major issue at the time was the Nunn-McCurdy Act report the Navy submitted. They significantly understated the over run costs by allocating costs to different sub programs. My office was generating a similar report. So, we reviewed USN drafts as a format and subject guide. About the time we realized it was flawed, the USN program office was relieved and the A12 cancelled. Our program chief (2 star) told us the USAF liaison officer told him Congress was sending a message.
