Indian Navy's TEDBF Fighter Program May Potentially Evolve into Full-fledged 5-Gen Naval Stealth Jet, Mirroring Air Force's AMCA Ambition

India's naval aviation capabilities could see a significant enhancement with reports suggesting the indigenous Twin Engine Deck-Based Fighter (TEDBF), under development by the Defence Research and Development Organisation (DRDO), might evolve into a fifth-generation stealth aircraft.

Information reported by ANI Media indicates the TEDBF is being considered as the naval equivalent to the Advanced Medium Combat Aircraft (AMCA), the fifth-generation fighter currently being developed for the Indian Air Force (IAF) by the Aeronautical Development Agency (ADA).

While there has been no official announcement confirming this shift, the possibility marks a potential major upgrade for the TEDBF. Originally envisioned as a 4.5-generation fighter, its evolution towards fifth-generation standards, incorporating advanced stealth characteristics, would align it technologically with the IAF's ambitious AMCA program and position it as a future replacement for the Navy's current MiG-29K carrier fleet.

The ADA is progressing with the TEDBF's design, aiming to complete its Critical Design Review (CDR) phase by early 2025, according to program timelines. However, it is not yet confirmed if this initial CDR phase includes modifications for advanced stealth features and an internal weapons bay (IWB).

Defence analysts suggest that integrating fifth-generation capabilities would necessitate substantial redesigns, including changes to air intakes, overall fuselage shape, and the integration of internal weapons carriage. This is considered a challenging but feasible goal, leveraging technologies already being developed for the AMCA project.

Notably, the AMCA program achieved a significant milestone with the completion of its CDR in early 2024 and received approval from the Cabinet Committee on Security (CCS) in March 2024 for prototype development, estimated at around ₹15,000 crore.

The TEDBF project, meanwhile, anticipates seeking CCS funding approval around 2026 to adhere to its proposed schedule, which targets a rollout by 2030, a maiden flight in 2032, and potential induction into the Navy by 2036. DRDO leadership has indicated the TEDBF program remains on schedule.

The Indian Navy's interest in a domestically produced fifth-generation fighter stems from clear strategic needs within the Indian Ocean Region. The development comes as global naval powers deploy advanced carrier-based stealth aircraft, such as China's J-35 and the United States' F-35 variants. Achieving parity requires comparable technology.

The TEDBF is expected to be initially powered by imported GE F414 engines, similar to those selected for early AMCA prototypes, with plans for a future indigenous engine potentially delivering 110kN thrust – possibly benefiting from the technology transfer arrangement secured for the AMCA engine co-development with GE.

Key performance goals for the TEDBF include a combat radius of approximately 1,000 kilometres and a top speed of Mach 1.6. Its design aims for multirole capabilities, encompassing air dominance, ground strikes, and anti-shipping missions.

Incorporating stealth features and an internal weapons bay would significantly enhance its survivability and lethality, allowing covert carriage of advanced munitions like the Astra Mk3 air-to-air missile or various Rudram-series missiles.
 
TEDBF stealth design with IWB or AMCA naval variant would have been a better choice by IN rather than going for 4.5th gen fighter TEDBF.

It looks like Rafale is going to win the G2G deal for 110 fighter jets, so if IN has any further requirements, let's say follow-on 13 after the initial 26 Rafale M jet order, can be met from Dassault's local subsidiary which wants to buy DRAL's 100% stake.

While it would be ideal to have a naval stealth 5.5th gen AMCA variant, with this project, the cost can be shared and development costs saved with 70% commonality plus an existing ecosystem. Two different projects would cost ₹15000 Cr for AMCA and ₹13000 Cr for TEDBF.

There is no point in developing TEDBF; IN should consider the AMCA naval variant.
 
AMCA-N would have been a far better choice. Some changes in the design and other relevant aspects and you were good to go. But DRDO is DRDO as usual.
 
Don't get stuck in 4th, 5th, 6th gen arguments... development should follow the timelines so that there is no capability gap in future. CCS should have cleared the project by now.
 
It takes a well-read person on a different orbit to write these kinds of flights of fantasy articles. Here, Mk1A is delayed 1 year plus counting, Mk2 is delayed 2 years plus and counting, 40 Tejas Mk1 aircraft take 14 years to be delivered and day-dreaming of TEDBF and AMCA. Wonder what these people are smoking?

If you do gain sense and get back to reality, can you let us know how many Mk1A will be delivered in 2025 and when will Mk2 fly? The “HAL” date… which means there will be minimum 2 delays to these dates.
 
Turning it into 5th generation would invariably delay the project, its a good idea but then they would have to order some more Rafale N to offset the delay. Timelines are important.

Naval AMCA is not that feasible as none of our AC is CATOBAR because of internal weapons bay, their range gets compromised due to less fuel carrying capacity, and in STOBAR type carriers, fighter jet solely depends on engine full thrust that also consumes lot of oil. Less weapons carrying capacity by fighter jets on STOBAR carrier and 5th gen jets would be too costly to maintain considering their budget.

Considering navy budget and capabilities, AMCA-N would be a good option although it can be used from their ground naval bases and in Andaman and Nicobar to counter Chinese threat but currently not feasible enough to operate from STOBAR.

How can the cabinet clear anything until they complete the CDR of the entire jet, negotiate contracts, negotiate price and then once everything is done and ready they can then finally send it to the CCS for fund approval?

We are still a long way off before it reaches the CCS so stop blaming the government.
 
It’s impossible to switch from a 4.5th generation jet and modify it into a 5th generation jet. If we want a 5th generation stealth jet then they will have to develop an entirely new jet from scratch which will take years. The navy rejected this option because of its high purchase and operating costs. It will also have a poor serviceability rate as the salty ocean waters and high humidity would corrode the stealth paint away very quickly. To avoid this they would have to keep painting it regularly just to maintain its stealth capability which is very expensive.

AMCA Naval variant was tried, but it's cancelled because AMCA can't be modified for marine variants beyond a point. That's always the issue when air force variants are made first. That's why F-35 faced critical issues to make naval versions and finally had to make something like VTO, which further complicated things like maintenance.

So it's always better to have separate planes for Navy, designed for carrier operations only.
 
IN looks hesitant because high cost involved in maintaining 5th gen jets in corrosive marine environment. But technology is moving at fast pace. Work on new materials and depend less on ram coating for stealth fighters.
 
TEDBF is a 4plus generation jet for naval use.
AMCA is a 5th generation stealth fighter for Airforce use.
The technical features and roles are different
