IAF Seeks to Keep MiG-21 Bison for Some More Years Amidst Delays in F-404 Engines for Tejas Mk1A

The Indian Air Force (IAF) eyeing to extend service life of its aging MiG-21 Bison fighter jets due to ongoing delays in the delivery of Tejas Mk1A aircraft. The delays stem from a shortage of F-404 engines supplied by GE Aerospace, a critical component of the domestically produced Tejas Mk1A.

This decision comes as a setback to the IAF's modernization plans, which heavily relied on the timely induction of the Tejas Mk1A to replace the MiG-21 Bisons. Originally slated for complete retirement by 2025, the MiG-21s will now continue to fly, albeit at a reduced operational tempo, until sufficient Tejas Mk1A jets are delivered to form a full squadron.

The IAF had planned to establish the first Tejas Mk1A squadron in July of this year at Nal airbase near Bikaner, the current home of the last operational MiG-21 Bisons. However, the engine supply bottleneck has hampered production at Hindustan Aeronautics Limited (HAL), the manufacturer of the Tejas, pushing back the timeline.

The MiG-21 Bison, despite undergoing numerous upgrades since its introduction in the 1960s, is now well past its intended service life. While it has a long and storied combat history, the aircraft has also been associated with a number of operational accidents, raising concerns about its safety record.

The Tejas Mk1A, a lightweight multirole fighter, represents a significant leap forward in capability compared to its predecessor, the Tejas Mk1. It features advanced avionics, an AESA radar, enhanced electronic warfare systems, and expanded weapons carrying capacity.

Despite the delays, the IAF remains committed to the Tejas program. With the first Tejas Mk1A jets expected to arrive soon, the IAF is focused on completing squadron formations and ensuring operational readiness.

The IAF has 83 Tejas Mk1A fighters on order and plans to procure an additional 97 by the end of this year, underscoring its faith in the domestically developed platform.

This situation highlights the challenges faced by India to develop and produce advanced defence technology. Supply chain disruptions, particularly for critical components like engines, can significantly impact India's military modernization programs and force adjustments in strategic planning.

India currently has no option but to delay retiring them and just use them as a last resort only. They should also use their trainers on the front line which can reinforce the existing Mig 21 squadron on our front line. If that’s not possible then we should deploy the Mig 29, jaguar, mirage and tejas to help them. We can also buy used jets but in good condition jets temporarily until we start receiving our jets from HAL and maybe in the future from private companies.

First of all I don't belive that narrative (allegedly shot down) and government fault because what have they done to improve that. In 2014 we had around 4-6 ioc Tejas we are currently at 32 or near. In 10 year 30-35 aircraft it's shameful. And they should have sped up the MMRCA process. Which they have stalled and HAL and all companies do what the government wants to do. They are government owned companies

If you don’t believe that we shot down their jet then you’re delusional. Evidence was provided and the whole world knew it was true including the USA and Europe otherwise why would Pakistan be so angry and want to attack us if we didn’t even kill their jet? Why was there a clear shortage of jets in one of its squadron.

Also HAL didn’t receive any large jet orders until recently when we started to place small orders at a time from initial operational clearance to final operational clearances and were ordered in batches with the maximum capacity of 8 jets per year although they never managed to achieve that. Recently we will get the private detective as well as he’s a fake cop.

Well it’s true that we downed a more advanced jet with superior capabilities from a 60 year old jet.

Also how is it the government fault when they placed a large 200 Tejas MK1A order but HAL, general engine, and the private sector companies failed to deliver the jets on time? HAL is the only company that has the capability, technology, money, financial stability and facilities as no private company has the same requirements to manufacture the entire planes rather than just supplying parts and components like they currently do.

HAL has the capability? 🤣🤣🤣 We are yet to even get the trainers for which engines have been delivered. As for financial stability, GoI gives all the money. Many bigger companies exist as well. So that is not a big deal. Coming to technology, it is given by ADA. It's just facilities which are missing, which can be developed when money is available.

Americans want india to buy f16 for MRFA tender that's why they deliberately delayed engines they are also pressuring government for same

whatever u call Geopolitical or Arm twisting Bharat will not bend the pressure which ever Fighter jets meets the MRFA Requirements will b winner , US tring to sell the Either one of its Fighter jets out 3 , It will b negative impact & reputation of its Jets Future sale if it lost on Tech parameters

It has the capability but its delays in manufacturing are the problem. As I said HAL has financial stability because it’s owned by the government. Also there are big private companies that manufacture parts, components, equipment and technology but they have never manufactured an entire jet by themselves and they have mainly just supplied parts.

 

[Bijaya Kumar Sahu]

Just imagine if GE says F404 engine will no more be produced then Tejas MK1A will be gone. No plan-B for alternative engine. Now HAL knew how unreliable is GE.

There are 2 jobs that HAL has to do. Manufacturing and development.

Tejas Mk1 trainers are delayed, which shows there is no capability in manufacturing.

Tejas Mk2 roll out is delayed by decades, so is the HTT40, which shows there is no capability in R&D.

So where is the capability?

There are many other companies which have just as much financial stability as HAL. If you look at the corporate bond yields of RIL bonds, they manage to do better than even GoI bonds at times. So there is enough financial stability in the private sector companies as well.

The United States has consistently delivered all other military equipment on time. However, when it comes to a specific part or component that could enable India to become self-reliant in its defense industry, there are, inexplicably, supply chain issues. This raises concerns about the true intentions behind these delays. 🙂
