Key Points and Summary – Grumman’s “Super Tomcat 21” was the Navy’s road not taken after the A-12 collapse and the NATF sticker shock.
-Building on the F-14D, the ST21 promised supercruise F110s, extra fuel in enlarged glove bays, digital flight controls, AESA-class radar and modern EW, turning the Tomcat into a long-range fleet defender and precision striker.

-The Navy chose the cheaper-to-own, versatile F/A-18E/F instead.
-This piece examines what might have been, mapping a realistic upgrade path to a speculative “ST2010” with networked sensors, satellite datalinks, and advanced weapons—suggesting how a revitalized Tomcat family could have changed carrier air wing range, magazine depth, and deterrence in the Pacific.
What if the Navy Had Chosen the Super Tomcat 21?
In a long-form feature for The War Zone, Tyler Rogoway just explored one of the greatest “what ifs: of U.S. naval aviation: the Grumman F-14 Super Tomcat 21 (ST21).
Conceived in the early 1990s after the collapse of the A-12 Avenger program and the Navy’s own Advanced Tactical Fighter initiative, the ST21 was pitched as a low-risk, high-reward evolution of the existing F-14D – the final, modernized variant of the F-14 Tomcat fighter.
Rather than gambling on entirely new designs, Grumman argued at the time that the Tomcat could be expanded into a next-generation fleet defender and strike fighter using relatively mature technology already available to them. The Navy, however, ultimately opted for the F/A-18E/F Super Hornet – Boeing’s twin-engine, carrier-capable strike fighter – leaving the Super Tomcat as an unrealized chapter of aerospace history.
Rogoway, working with aerospace artist Adam Burch, attempted to show readers exactly what was lost when the Navy chose to go a different way. In the piece, Rogoway and Burch built detailed digital renderings of the proposed Super Tomcat 21 and then went further, imagining what future evolutions of the aircraft may have looked like had the Navy chosen to continue investing in the platform. The result? A proposed “Super Tomcat 2010” (ST2010) – a hypothetical upgrade package that features the most powerful fighter AESA radar ever fielded, modern electronic warfare systems, satellite data links, and advanced weaponry.
Though only a hypothetical design, the piece outlines a realistic scenario in which the Navy chose a different path.
The History
Before we dive into the proposed designs from Rogoway, let’s first take a look at the history that makes the story of the Super Tomcat so interesting to naval aviation enthusiasts.
Following the cancellation of the A-12 Avenger II in 1991, the U.S. Navy found itself with a major capability gap. The A-12 had been intended as a stealthy, all-weather, carrier-based attack aircraft that would replace the A-6 Intruder – but cost overruns, increasing weight, and various delays ultimately saw the program canceled. At the same time, the Naval Advanced Tactical Fighter (NATF) program, which would have been a navalized equivalent of the U.S. Air Force’s ATF, was proving too expensive and far-off for near-term operational needs.
Grumman responded by pitching incremental growth designs built on the existing F-14 platform. One such design was known as the “Quick Strike,” a modest upgrade to existing F-14s that included targeting/navigation pods, improved ground-attack radar, and standoff weapon capability that could pick up the slack from the retiring Intruders.
But recognizing that Quick Strike was seen as insufficient, Grumman proposed a more ambitious “Super Tomcat 21.” The design would include more powerful engines, upgraded radar, targeting pods, loiter capability, and improved standoff weapons.

Grumman argued that adopting its ST21 platform was a lower risk and more cost effective option, leveraging existing, mature technologies rather than leaning on entirely new, unproven, or cutting-edge systems. The idea was that the ST21 would become a near-term solution that would relieve the Navy of its reliance on new, high-risk platform programs – and extend the relevance of the F-14 well into the next century.
But it wasn’t to be. The Navy chose the Super Hornet, and they did so for multiple reasons ranging from budget concerns, maintenance costs, and the complexity of the F-14’s variable-sweep wing system. The Super Hornet, meanwhile, was seen to be a better fit for the Navy’s shifting strategic priorities, offering versatility, a lower life-cycle cost, and multirole capability.
The ST21 That Never Was
The ST21 was conceived as a logical extension of the F-14D rather than a radical new aircraft platform. Grumman’s proposal centered on taking the proven Tomcat airframe and addressing its key weaknesses while building on its strengths.
At the heart of the new aircraft were new F110-GE-429 engines, powerful enough to give the jet true supercruise capability – meaning it could sustain supersonic flight without afterburner while carrying a combat load. The aircraft’s enlarged wing gloves were designed to house additional fuel, which would extend range and endurance while its new digital flight controls and aerodynamic refinements promised better low-speed handling and overall performance.
The cockpit would have been radically transformed, too, with a single-piece windscreen, a wide-angle head-up display, as well as glass displays that were connected to upgraded computer systems. The radar system would have been reworked, based on the APG-71 and incorporating features already included in the F-15E Strike Eagle.
An impressive range of weapons were on the table, too, including standoff munitions, AIM-120 AMRAAMS, and potentially improved Phoenix missiles. Incorporating those kinds of weapons would have turned the Tomcat into a long-range fleet defender as well as a precision strike platform.
The ST21 – the aircraft that never was – was pitched as the aircraft that could finally fulfill the full potential of the Tomcat. It was fast, powerful, equipped with advanced targeting technology, and importantly, versatile. And had the aircraft been built as planned, there’s no telling what the family of aircraft built around it could have become.

Unfortunately the actual demise of the Tomcat was pre-destined in the 70’s when what some considered arrogance the Navy Fighter Community resisted efforts to develop its Ground Attack capabilities. That decision led the Marine Corps to abandon plans to replace 12-14 Phantom Squadrons with F-14’s since the Tomcat could not offer Close Air Support to Ground Troops and wait for the Hornet. After the introduction of the Multi-Role F-18 Navy leadership realized the mistake and finally upgraded the plane into a highly capable Attack Aircraft with impressive Bomb Loads and Sensors but it was too late and Maintenance costs per flight hour were excessive due to the old technology used in the original design.

To Jack n Bill – I wish there were many more comments on here but let me address both of yours – Sadly the Cat and What Grumman Aerospace was and stood 4 are both gone and will never be back. What I’d like u both to know I’ve responded to many – hundreds in fact of inaccurate comments – videos or articles at the request of my now deceased father with most actually all but 1 from Australia incorrect or inaccurate facts that people like yourselves are just plain wrong and you call it TomCat gospel!
It was (plain n simple) Then VP Dick Cheney who during the early 80’s had a personal grudge against Grumman and carried that with right till 1996 when he put the company outta business (personally) and did his utmost best to cover that up. Why don’t u both go to Kong Island NY where I’m from n get ur shit straightened out! It had nothing to do with Cost as in google what the National Debt was in 1996 n compare that to today – It wasn’t obsolete as in we have the brand new F-15 and it wasn’t maintenance because the 21 addressed most of the Maintenance issues of the 14 – I’ll end by saying Dick used the power of the Fed to personally put a company out of business because of a grudge Dick had and rather than cow tow to a scum bag Dick was told pound sand – With that my father was an airframe engineer 4 Grumman – he started in 65 as an accountant with a background from the USAF of both Pilot n Mechanic – Mr Grumman asked my dad to go to engineering school over @ Farmingdale NY in67 so by 69 more early 70’s my father worked on the: A6-E – the E2-C the never built A6-F – All Tomcats n the never built Tomcat 21 – research that n compare that even to today’s F-15 btw I’ll take the Cat Anytime Baby – Signed Al Schneider – the proud son of a Grumman Airframe Engineer.. PS I could write a novel as too why Dick Took out Grumman but I don’t want to write anymore and it doesn’t change the past – I do hope it changes the future as Govt should not have the power to decide the winners or losers in the Private Sector
