FOC is irrelevent now, MK.1A is the focus- everything HAL is doing these days is with MK.1A in mind, FOC for Mk.1 doesn't mean much when only 40 Mk.1 will ever be produced. Mk.1A will be the game changing moment for the LCA project.
bro mk1a is the optimized version of foc ..

we will see features with some extra features like aesa ,jammer in mk1a....so without foc Hal can't go for mk1a ....

again after 2nd production line. start s delivering Hal will deliver 16+jets
8 from first production line +8 from 2 nd production line +2 from converted line ..+ Hal is out sourcing components ....so we can see more Tejas

Until the full squadron is formed, It will be stationed at southern India ..
Had read a long time back that until 1st Sqn reaches sqn strength it will be at B'lore, then will be relocated to Sulur TN, which is near HAL until logistics infra and service protocols are ironed out and streamlined. Once Orbat/ combat techniques are defined and SOPs are firmed up they would be moved to appropriate commands.

Absolutely wrong. The only similarity Mk1 and Mk1a has is airframe, engine, and cockpit. Everything has to be done from the ground up. Even the airframe and LRU will see subtle changes for the good which relegates to ease of maintenance.

Adding a new radar means doing everything from scratch. So even if they skip FOC or achieve it, it becomes irrelevant for Mk1a because they have to carry out all the integration test again.

So even they skip FOC which is unlikely due to the contract they can directly go for Mk1a. It doesn't make sense because that will eventually delay the program further. They already had fire handful of the weapons and carried out integration on ELTA 2052.

So in short FOC achievement has nothing to do Mk1a because they eventually have to integrate all the weapons, modes and EW suit with whatever new radar they pick.

1 line is producing 6-8, the makeshift line has 4 and the new sanctioned line has been slated to deliver 8 + whatever else comes from 3 party companies.

Radar change doesn't change everything. Radar is a modular unit and not incorporated into fly-by-wire. Radar is not needed to fly but for surveillance and target acquisition. There is 0 automated response embedded in fly-by-wire to take inputs from Radar. So, one doesn't make it from scratch but just integration of weapons and communication systems. It requires time but "not from scratch".

^^ Where did I said anything about flying?

From scratch, I meant with respect to the conversation above i.e. FOC. Read the post again in the context of FOC.

The poster above said FOC is imperative for Mk1a which is inane.

A new radar will lead to the similar steps that are needed for FOC and more. You have to foolproof radar operating modes, weapons, integration of various suit, integration of the radar with avionics. It especially becomes cumbersome in case of Uttam considering it comes fresh out of the oven.

Private companies to carry out 70% of production work for Light Combat Aircraft Tejas

BENGALURU: In a move that will help meet delivery deadlines, defence PSU Hindustan Aeronautics Limited (HAL) has decided to outsource majority of the production work of Light Combat Aircraft (LCA) Tejas. The move will see private firms make nearly 70% of the aircraft.

Presently, HAL is manufacturing LCA Mk1 and is a working on the ramping up of production capacity from eight to 16 aircraft per annum, which it expects to happen by 2019.

"Major sub-assemblies such as front fuselage, centre fuselage, rear fuselage, wings et al, have been outsourced to private industry. The orders have been placed and they need about an year to supply these. Soon, nearly 70% will be made by our industry," a senior official part of the LCA project told TOI.

About 85 vendors (private firms) will be involved in the production of LCA. Some major players are: Dynamatic Technologies Ltd, Bengaluru (front fuselage); VEM Technologies, Hyderabad (centre fuselage); Alpha Tocol, Bengaluru (rear fuselage); L&T, Coimbatore (wings); while the tail fin and rudder will be supplied by National Aerospace Laboratory and Tata Advanced Materials Ltd.







"With increased level of outsourcing and capacity within HAL, we will be able to speed up the deliveries to cater to the present and future requirements of our customers.Enhanced outsourcing is the norm being followed across some important projects at HAL. For example LCH production will involve outsourcing as a major strategy," another senior HAL official said.

HAL has established a second line series production of Tejas, which has come up at Aircraft Division and is being equipped with full-fledged assembly jigs. HAL's plan for expanding Tejas production to 16 fighters per year involves establishing a second assembly line. This has physically replaced the Hawk trainer line.

5 delivered, 6th Tejas soon

The number 45 squadron (Flying Daggers) of the Indian Air Force (IAF) has already taken possession of five LCA Tejas aircraft and will soon have the sixth one. "The sixth one is expected to fly in the next three days and the seventh in about 10 days. By end of March 2018, we hope to deliver 11 planes (including the five delivered)," the official said.


For the first time, the IAF squadron completed the armament detachment—weapons firing—in September and October this year. "That was the proof of the pudding. It was not a developmental test, the squadron that will fly and fight has completed the detachment, and we were glad that it was successful," an IAF source said.

The Flying Daggers Squadron is presently operating from HAL in Bengaluru, but will eventually move to its official base in Sulur, Tamil Nadu.

Tejas, which was first conceived in the early 1980s and officially approved in August 1983, is an indigenous fighter that has undergone several changes before being accepted by the IAF in January 2015. While the first 40 aircraft will be supplied in the present configuration, the IAF has sought more improvements for future ones.

The winner will provide modified radar and EW which is compatible with the existing systems on Tejas ..
Yes, and everything will work out of the box by replacing radar. All the missile will be integrated and whatnot.

Who told that changing radar is that easy ...
You need to take lot of things into consideration like size, weight,cooling power, cabling.
If the radar size changes we need to re design the cone to incorporate it.
You think that easy like changing a light bulb.

Have you heard of T/R modules? These are reduced/increased to adjust the size. The cone is never adjusted as that will affect fly-by-wire and flight stability. Radar size are different for different planes and rely on power of engine, size of cones etc. As of now, MK1 have a ballast in place of radar in special series production to compensate the weight imbalance. The ballast will be removed for radar. These are all well planned.

Even the coding of radars are made like the pen drives which can be plugged in and out. So, any Indian radars be it GaAs or GaN, can be simply replaced. The only difference will be in technology of T/R modules and not the functioning. Problem comes when integration of foreign radar is done on Tejas avionics which can lead to instability.

If India gets to write the codes of the radar while only replacing the modules, then it is possible to work out of the box.

My suggestions to Make Mk1+ the dedliest of all planes.

1) reduce the weight bellow 6000 KG (WHich is very much possible)
2) Make proposed aerodynamic changes to reduce Drag by 8% (New design is already proposed)
3) Redesign pilot seat with less inclination and Use the space to carry out more fuel (This will automatically take care of dead wight used in front portion)
4) Use EJ 230 engine inplace of GE404 with 73 KN Dry and 108 KN weight thrust.

This will kick @$$ of Saab Gripen and F 16. Forget about JF 17 Blunder and Junk 10.

Have you ever seen T/R modules?
They are fitted to a radar shaped base,they are not Lego's.Go to you youtube and see aesa radar videos.
Size of cone decides the range and desired wavelength of the frequency.
I know the radar are different for each plane and there don't depend on engine power because there is small generator to generate power for aircraft.
Pen drive plug in and plug out...:rofl:
Some one please teach this guy few basics

The design change will be in Mk2. MK1 will involve same desig and all these can't be incorporated. Tejas MK2 can't beat F16 as F16 is much bigger. But, if cost wise seen, Tejas will cost 20-25% of F16 when mass produced and hence beat it.

Frequency doesn't depend on size of the cone but the transmission module.
Radar power doesn't depend on engine in general as the power generated is significantly higher and minor variations don't change anything. But it does matter when there is big difference like drones.
Size of cones means more number of transmission/reception modules can be placed for better signal strength and hence range. Range of radars depend on the T/R numbers/strength/power which depends on space available and hence on cone size.
Pen drive type plug works if the programming of the radar is Indian while only the components are imported.

PS: It was not number of T/R module but number/strength of T/R.

F16 can only have a chance against LCA in low Mach nos, with sustained maneuverings, LCA beats f16s by very big margin in Mach nos above0.6. Usage of all electronics at peak poweroutput declines the aircraft's physical performance on air. Indeed strength and power output matter than increased nos of tr modules.

About F16 vs Tejas, Tejas is a better plane in terms of cost and mass manufacture ability. However, India is highly populous country and hence Tejas is suitable for India. Tejas is unfit for countries like Israel as they have low population. USA doesn't prefer delta wing for this reason- US is risk averse. Tejas is not highly maneuverable in sustained manner as delta wings bleed energy while swept wings don't. The main point here is - DELTA WING. Delta wing makes the plane naturally sturdy and reduces number of parts, has high instantaneous maneuverability but is overall consumes higher fuel and is not sustained maneuverable. While comparing F16, we have to consider 4Tejas vs 1 F16 to make up for cost difference and even out the advantages and disadvantages.

Gripen is just an assembled assortment and not worth considering for comparison.

Acc to research, the Tejas mk1 outperforms F16A/B in STR in high Mach NO. WHILE completely outperforms f16C/D
In any Mach no. F16A/B can only survive in a dogfight with LCA in low Mach no on sustained maneuvering andaking LCA bleed energy without getting favourable condition of suiting which after HMD is highly unlikely..... New F16s are dud in any format against LCA in any Mach no.

LCA isn't cheap after aesa radar, integrate ew suite smart weapons...... One aesa module itself cost 1000 dollars if it's is GaA.
