LCA Tejas Mk1 & Mk1A - News and discussions

June 2019 ?
Hopes are always for dates earlier than deadline. Deadline is Decembern2018 and hopes was june 2018
And anyone what is the time required for rolling out a Tejas from the factory line? Means from start to end?
For Tejas it is 7months from start to end assuming all parts are available (no delay in imports for imported components). The composite airframe reduces the number of fasteners and bolts required and makes the assembly faster
 

here is what is in the report:
As far as the FOC order is concerned, mid-2018 is when FOC is expected to come but we are asking the customer (IAF) to allow us to cut the material.

While the promises are for getting the FOC by mid-2018, we will definitely get it by December 2018. We should then be able to supply these 20 FOC by 2022. And then on to the next 83

Yes 'june is hopeful date but december is guaranteed deadline' was my interpretation of it. Did I say anything wrong?

December 2018. HAL has been giving this deadline since 2017. Suvarna Raju himself said that the deadline is december but the hopes and attempt will be to make it by June 2018

promises are to give the FOC by mid 2018 - this is not "hopeful" this is "promised" date.
if you are not sure to get it by June - then you dont give a "promise".
 
  • Agree
Reactions: Volcano
Then what is december deadline for? How can there be 2 promises? Understand the meaning of the words. People can make mistakes while speaking as speaking is generally too fast

thats the head of HAL - he should be careful with his words.
there cant be two promises. he used the word "promise" with mid 2018 date. he has not met it. now will anyone trust his "promise" any more?

He spoke the two in the same breath and gave relative emphasis to december. Also, promise here only meant expectation or hope, not "pinky swear"
 
Still can you state a date when FOC will be achieved?

The only thing left is one last test in refuelling. It's basically a done deal since the LCA has already finished hot refuelling tests. They have said it will come this year, and you can consider this the final date, no more postpones. An exact date is yet to be decided, they have to make a function out of it after all.
 
Read in BR that actually even refuelling is delinke from FOC .

These features are for Mk1A.

Why delays then ?
 
LCA-Tejas Program under IAF Soon, MK-2 flight by 2023 to surpass Mirage-2000 performance – Indian Defence Research Wing
LCA-Tejas Program under IAF Soon, MK-2 flight by 2023 to surpass Mirage-2000 performance

The government is poised to hand over control of the Bengaluru division of State-owned Hindustan Aeronautics Limited (HAL) to the Indian Air Force (IAF). This is to prevent more time and cost overruns on the indigenous Light Combat Aircraft (LCA) project. This comes at a particularly crucial time as the next phase of the LCA project, development of the MK2 variant, as well as the country’s next fighter aircraft programme, the Advanced Medium Combat Aircraft (AMCA), begin to take shape.
“The government has given the go ahead to hand over the entire Bengaluru complex of HAL to the IAF. With this, the fixed wing aircraft division will come under the IAF. The modalities are being worked out,” an official source told this reporter of the process that may take a few months.
HAL resists
HAL manufactures and assembles a range of aircraft and helicopters. However, it has faced criticism for its time and cost overruns and lack of professionalism in project execution. HAL has opposed this move for a long time, fearing erosion of its autonomy.
The LCA programme was sanctioned in 1983 and the aircraft made its first flight in 2001. The IAF had signed two contracts with HAL, one for 20 aircraft in the Initial Operational Clearance (IOC) configuration signed on March 31, 2006, to be completed by December 2011, and another for 20 aircraft in the Final Operational Clearance (FOC) standard signed on December 23, 2010, which was to be completed by 2016. It is in the process of ordering 83 jets in the Mk 1A configuration.
The IAF constituted the first LCA squadron with just two aircraft in 2016 and, as of July 2018, has inducted only nine aircraft. Tejas has once again missed the FOC in June and the development of the Tejas-Mk 1A with specific enhancements has been delayed. With this development, HAL’s aircraft division will be headed by a serving three-star officer or an Air Marshal of the IAF, and effectively give the IAF control over the country’s indigenous LCA project.
In addition, three institutions — Aeronautical Development Agency (ADA), Aeronautical Development Establishment (ADE) and Gas Turbine Research Establishment (GTRE) — which are under the Defence Research Development Organisation (DRDO) are likely to be brought under the direct control of the Chief of the Air Staff. Thus, the entire development cycle of the LCA will have the IAF’s oversight and will ensure timely execution and prevent blame games over delays, the source observed. Details of the specific contours of the move are awaited.
‘Long overdue’
“The IAF should have taken over the LCA programme two decades back, but [it is] good it’s happening at least now,” said Air Marshal M. Matheswaran (Retd), who oversaw the IAF’s fighter procurement in the past. He felt that to make a real difference, the IAF should get the entire cycle under its control, from design, standardisation, production and supply chain. Otherwise, just having one officer at the helm will not change things much, he added.
“Production for 20 FOC aircraft will be taken up after FOC clearance by the ADA, for which the current target is December 2018,” Minister of State for Defence Subhash Bhamre said in a written reply in the Rajya Sabha last week.
However, a Defence Ministry official said this is likely to be delayed by another six months as several parameters like gun firing, air-to-air refuelling and new data-linked software defined radios, among others, are yet to be validated. The IAF wants new data links as a standard feature on the FOC variant as communications are an essential feature for an aircraft to operate in a network-centric environment.
HAL is setting up a second assembly line to ramp up production from eight to 16 aircraft a year, in addition to outsourcing major modules to private partners.
Design reboot
The LCA is powered by an American GE-404 engine, which the IAF has stated is underpowered. This is to be corrected in the LCA-Mk2 which would be a larger aircraft powered by the GE-414 engine producing 98kN thrust compared to 84kN thrust of the current engine.
“The design change has been launched sometime back. We don’t want just some superficial changes, but a real increase in performance. The target is to meet or exceed the Mirage aircraft in performance,” an IAF official said.
To accommodate the larger and more powerful engine, which also needs more fuel, requires a larger wingspan for the aircraft. This calls for a major design and engineering effort.
“There are concerns and challenges but it is doable,” the officer noted.
The first prototype of the Mk2 is expected to make its debut flight in 2022-23, and complete the IOC and FOC approvals in the next five years. The current target is to have the first squadron ready by 2028.
The IAF intends to have several squadrons of the LCA-Mk2 as it has to replace three Mirage squadrons, three Mig-29 squadrons and six Jaguar squadrons. A squadron typically has about 18 aircraft, 16 fighters and two trainers. However, this can vary, depending on the type of aircraft and the necessity.
 
Production of Tejas Aircraft

For production of Light Combat Aircraft (LCA) Tejas, Hindustan Aeronautics Limited (HAL) has got orders from Indian Air Force (IAF) for 40 aircrafts {20 Initial Operational Clearance (IOC) standard and 20 Final Operational Clearance (FOC) standard}. 20 IOC contract was signed on 31st March 2006 to be completed by December 2011 and 20 FOC contract was signed on 23rd December 2010 to be completed by 2016. IOC for LCA Tejas was received in December, 2013.
The value of IOC contract for 20 No. Tejas aircrafts is Rs.2701.70 Crores (Revised to Rs.2812.91 Crores). Amendment in IOC contract has been sought for Rs.5362.17 Crores as part of Change Order on account of changes in build standards for Integration entailing procurement of additional Line Replaceable Units (LRUs), Raw materials, composite materials, Bought out items and consumables, tooling etc.
The value of FOC contract for 20 Tejas aircrafts is Rs.5989.39 Crores.
Out of total 20 IOC aircrafts, 9 aircrafts have been delivered by HAL to IAF till date.
Besides, 40 LCA Tejas aircrafts (20 IOC & 20 FOC), Defence Acquisition Council (DAC) has cleared acquisition of 83 LCA Mk1A aircraft with enhanced capabilities with Active Electronically Scanned Array (AESA) Radar, Beyond Visual Range (BVR) Missile, Self-Protection Jammer (SPJ) and Air-to-Air Refuelling (AAR) for which quotation has been submitted by HAL.
