HAL Tejas | Updates, News & Discussions-[Thread 2]

JF-17 is 14,520 lb empty. Tejas is 14,300 lb empty. 1 ton = 2,000 lb. Tejas is 220 lb lighter than JF-17, not 1 ton. Article wrong. :laugh:

welcome back !
yes, i know article is not accurate and not upto date ...
for eg jf 17 can carry 4000kg weapons now..

but its a good read, giving the plus and minus of both aircraft..
 
Drdo hybrid mmr 45km range vs An apg 68 120km range

Tejas is sitting duck

The one evaluated against 2m² targets and with the nose material issue, the other on 5m² targets, which makes them comparable again, if you choose the same target size. Rafael gives the EL 2032 with up to 136Km against a 5m² target and we know that the LCA has a pretty large nose diameter for it's overall size, therefor good detection range after the new nose is integrated, would not be that surprising. But that alone doesn't make it superior or inferior, it has it's good sides and it's bad sides, just as any fighter.
 



The enlightened one has made his triumphant return.

CAG picks holes in LCA project, says it fails to meet IAF


India's Tejas Light Combat Aircraft project, in the works for over three decades, came under severe criticism from CAG today, which said the Mark-I version has several shortcomings and does not meet IAF specifications.

Not only that, IAF would be "constrained" to induct the fighter LCA without availability of a trainer model, thereby "adversely impacting pilot training", the audit body said in a report tabled in Parliament.

The CAG noted that it was due to the delay in the manufacture and supply of LCA that IAF had to go for alternative temporary measures such as upgrading its MIG BIS, MiG-29, Jaguar, and Mirage aircraft at a cost of Rs 20,037 crore and revise the phasing out of MiG-21s.

Listing the shortcomings, the CAG said that the LCA Mark-I fails to meet the electronic warfare capabilities sought by IAF as the Self-Protection Jammer could not be fitted on the aircraft due to space constraints.

Also, it said that the Radar Warning Receiver/Counter Measure Dispensing System fitted on the aircraft had raised performance concerns which are yet to be overcome (January 2015).

The LCA Mark-I, which got Initial Operational Clearance in December, 2013, significantly falls short (20 permanent waivers/33 temporary concessions) in meeting the Air Staff Requirement (ASR), the CAG said, adding that that has led to reduced operational capabilities and survivability and, consequently, its operational employability.

It added that the shortcomings in the Mark-I (increased weight, reduced internal fuel capacity, non-compliance of fuel system protection, pilot protection from front, reduced speed) are expected to be overcome in the Mark-II model.

"LCA Mark-I does not meet the ASR. The deficiencies are now expected to be met in LCA Mark-II by December 2018," the CAG said.

While DRDO has always showcased LCA, christened Tejas, as an indigenously-developed aircraft and the indigenous content of the LCA was estimated by ADA to be 70 per cent, the CAG said it "actually worked out to about 35 per cent" as of January this year.

Systems such as Kaveri engine, Multi-Mode Radar, Radome, Multi-Functional Display System and Flight Control System Actuators taken up for indigenous development could not be developed successfully, resulting in LCA's continued dependence on the import of these systems, CAG said.

IAF had proposed in the early 1980s that a new aircraft be developed to replace the MiG-21 fleet, manufactured during 1966 and 1987, after its phasing out in the 1990s.

LCA will not be able to penetrate enemy lines


KALYAN RAY, NEW DELHI, MAY 08,2015, DHNS:

Tejas light combat aircraft
The indigenous Tejas light combat aircraft (LCA) will experience a major handicap in defeating the enemy due to non-availability and poor performance of three electronic warfare instruments, developed by Indian agencies.


During the trial, the all-important counter measure dispensing system that protects the aircraft against radar and heat-seeking missiles, could not do its job properly, leaving the jet with poor defence. The system was developed by , Hyderabad-based Bharat Dynamics Limited.

It was not the only faltering system on-board the LCA. The self protection jammer that blocks the enemy radar was too big to be fitted into the Mark-I version of the LCA and the radar warning receiver, which alerts the pilots on hostile enemy signals, perform poorly. Both were developed by Bangaluru-based Defence Avionics Research Establishment.


"LCA Mark-I remains deficient in full electronic warfare capabilities as specified in the Air Staff Requirement (ASR),” the Comptroller and Auditor General (CAG) says in a review report that was tabled in Parliament on Friday.

The aircraft, which achieved initial operational clearances on December 2013, has as many as 53 shortfalls from the specifications drawn in the ASR.


Some of the shortcomings like increased weight, reduced internal fuel capacity, pilot protection from the front and reduced speed are to be addressed in the Mark-II version that was taken up by the Aeronautical Development Agency in 2009 and scheduled for completion in 2018.

Even after 30 years, the LCA could get only the initial operational clearance (IOC) in December 2013. The full operational clearance (FOC) is now targeted in December, 2015.

The cost is also rising all these years. What began as a Rs 560 crore programme in 1983 has now gone up by almost twenty times. The financial package for LCA now stands at Rs 8294 crore.

The auditor also criticised the Defence Ministry for awarding two commercial contracts to Hindustan Aeronautics Limited (HAL) in 2006 and 2010 for delivering 20 fighter planes in each contract in the IOC and FOC configurations respectively to the IAF.

Both were termed premature because in 2006 LCA design was nowhere near finalisation, whereas in 2010 HAL was yet to supply any aircraft to the force as per the previous contract. Even now, the IAF is not in a to operationalise the LCA squadron in the absence of a trainer aircraft. Moreover, HAL’s production capacity - four aircraft per year - is only half of what the government wants.

It will, since the MMR is mainly based on the EL 2032, because the DRDO radar development could not deliver a useful system. Now the "hybrid" is mainly an EL2032, Indian subsystems and most likely the same will be used for the Jaguar upgrade, most likely with a smaller diameter though.

You are wrong.

The DRDO MMR which is on Tejas has 45km radar range and is NOT the El/M 2032 as the IAF Jaguars have with 150km Air-Air range and 300km Air-Ground/Sea range.

Tejas is hopelessness outclassed by its fellow 3rd platforms like Mig-21 Bison which has nearly double the radar range.

Fantasy figures at best.
