Why HAL Would be Debilitating the IAF with its Combat Hawk

HAL and BAE have plans to co-develop in India a combat variant of the Hawk AJT for use by the Indian Air Force, as also for export to friendly countries.

In May 2015 HAL and BAE Systems UK signed a MoU that included development of Combat Hawk besides upgrade of Hawk Mk132 and maintenance solutions for supporting Jaguar and Hawk fleet.

HAL and BAE Systems discussed the Combat Hawk in London during Prime Minister Narendra Modi's visit to the UK in November 2015.

A BAE Systems' Director of Hawk Aircraft Programs, Alun Fishburne, recently told Janes.com that his company is negotiating sale of additional batches of Hawk training aircraft to India, beyond the order for 20 Hawk Mk.132s for the IAF's Surya Kiran team currently being finalized.

The BAE official's reference to additional batches suggests that Indian procurement would go beyond attrition replacements.

HAL and BAE's enthusiasm notwithstanding, the project to co-develop the Combat Hawk makes no operational sense.

As a Lead In Fighter Trainer (LIFT), the Hawk Mk132 is already capable of carrying a wide variety of external stores for weapon release training. The aircraft reportedly has 7 hard points to carry external stores with a possible 12 types of combinations to carry the stores.

The proposed Combat Hawk will likely feature:


  1. An advanced weapon aiming subsystem
  2. Tighter integration of the weapons and cockpit avionics
  3. An integral gun


Other possible feature could include:


  1. A laser rangefinder for more accurate weapon delivery
  2. A TV camera for easier identification of targets
  3. Close Combat Missiles
  4. A refueling probe


Considering that the Hawk is a single engine aircraft with a low thrust to weight ratio (0.65) the Combat Hawk would at best be a counter insurgency (CI) aircraft.

The problem is, the IAF has no need for a CI aircraft! The IAF is not tasked for CI ops and has shied away from the role in past and ongoing insurgencies, with good reason.

What the IAF needs is a dedicated Close Air Support (CAS) aircraft capable of operating in the mountains along the LoC and LAC. A dedicated CAS aircraft needs the safety of two engines, a design optimized for absorbing punishing ground fire, a titanium bathtub to ensure crew safety, a high T/W ratio to ensure good maneuverability in narrow valleys at high altitudes, and adequate Suppression of Enemy Defense (SEAD) capability. The Combat Hawk will have none of these features.

Yes, the IAF has no need for the Combat Hawk. As to export...really?

Clearly, the Combat Hawk is being pushed by HAL for self serving reasons. HAL has stabilized local assembly of the Hawk after a lot of struggle. Additional IAF Hawk orders would ensure easy profits for the very inefficient public sector behemoth for many years running. Despite having struggled with just the local assembly of Hawk Mk132, HAL is disingenuously projecting Combat Hawk as the next big Make-in-India success story.

Mislead by the HAL, the government may well go along with the Combat Hawk project, since it would also keep the UK happy. If that happens, it would be a case of diplomacy dictating defense capability, not the other way around, as it should be!

News Roundup: AMCA Project Stranded without Engine, Army Clears Dhanush 155mm/45cal Gun Production and More

Dhanush at DefExpo 2014

Army grants OFB Bulk Production Clearance for 144 Dhanush 155-mm/45-cal guns 


The Indian Express reported on July 6, 2015 that the Indian Army has granted OFB (Ordnance Factory Board) Bulk Production Clearance for 144 Dhanush guns.

Gun Carriage Factory, Jabalpur has already started production of the gun; it plans to supply 6 guns within 6 months, another 12 within 12 months and another 36 guns within 24 months.

Army had hoped to get all the 144 guns in 3 years!

The MoD announced on April 27, 2015 that Dhanush has met all tech parameters in Winter and Summer Trials.

The TOI reported on October 13, 2014 that field trials of the gun have been completed and OFB is currently waiting for the DGQA report on the trials.

Hawk AJT Flight Safety Record

On July 6, 2015 the TOI reported that the recent Hawk AJT crash was attributed to quill shaft failure, leading to concerns about HAL production quality.

A source reportedly told the TOI that Rolls-Royce has reduced the TBO (time between engine overhauls) of HAL produced Hawk AJTs from 2,000 hrs to 1,200 hrs, as a result of production quality concerns. HAL has denied the allegation.

On June 3, 2015, an IAF Hawk crashed about 50 Km west of Kalaikunda airbase. Both pilots ejected safely.

The crash was the second IAF Hawk crash. The first, was attributed to human error.

AMCA Powerplant


On July 6, 2015 the Business Standard reported that the US is stonewalling India's request for cooperation on developing hot engine technology - specifically, India's desire to fund residual development of the F414 EPE as AMCA powerplant.

As a result, MoD is issuing a global tender, inviting aero engine majors to co-develop with the DRDO an AMCA powerplant.

The US stonewalling will bring back Eurojet EJ200 as contender for powering the AMCA. Eurojet reportedly convinced the DRDO it can uprate the EJ200 to 110 kN.

One good reason for the US to stonewall joint development of the F414 EPE for AMCA could be concern over Indian plans to fit the AMCA engine with thrust vectoring nozzles developed with assistance from Russia's Klimov.

Russian engine technology lags behind the US state-of-the-art, and the US could be worried that the Russians will get a close look at the F414 EPE. However, Russia claims that its Item 30 engine being developed for the PAK/FA would match contemporary western aero engines. The first prototype of the Item-30 engine is due to be delivered later this year.

Pinaka Submunition Warhead Development


Pinaka rockets were successfully tested with submunition warheads, including a thermobaric  warhead, at Pokhran during field firing trials in Rajasthan on June 29, 2015.

The tests were conducted using random Pinaka Mk-1 rockets picked up from a production lot. [via TOI]

The submunition warheads tested are among the eight kinds of warheads for Pinaka. Thermobaric  warheads are deadly against personnel and inflammable targets. Other warheads developed include cluster warheads armed with anti-personnel and anti-tank submunitions., and runway denial penetrating submunition warheads, aimed at neutralizing targets like runways and other complexes.
