NEW DELHI/BANGALORE — Lockheed Martin offered India on Wednesday a new combat jet to be made locally, the F-21, in an attempt to win a large military order worth more than $15 billion.

The US defense firm had previously offered its F-16 fighter used by countries around the world for the Indian air force’s ongoing competition for 114 planes to be made in India.

But Lockheed, unveiling the plan at an air show in the southern city of Bengaluru, said it was offering India a new plane configured for its needs.

It would carry technologies from its fifth generation planes, the F-22 and the F-35, the firm said.

“The F-21 is different, inside and out,” Vivek Lall, vice president of Strategy and Business Development for Lockheed Martin Aeronautics, said in a statement.

The company will build the plane in collaboration with India’s Tata Advanced Systems, the firm said.

Lockheed is competing with Boeing’s F/A-18, Saab’s Gripen, Dassault Aviation’s Rafale, the Eurofighter Typhoon and a Russian aircraft for the air force order.

The deal to replace the Indian Air Force’s ageing fleet of Soviet-era fighter jets is one of the biggest contracts for such planes in play.

India has a lengthy procurement process, and no decision is expected until well after a national election due by May.

Lockheed has offered to move its F-16 production plant at Fort Worth, Texas, to India, if it wins the order in a boost for Prime Minister Narendra Modi’s Make-in-India plan to build a domestic military industrial base and create jobs.

It said it expected to export planes from the proposed plant in India on top of the Indian requirements for an overseas market that it estimated at $20 billion.

But the Indian military has had concerns over the F-16 as an old plane and in an earlier competition it lost out to the eventual winner, the Rafale built by Dassault.

But Lockheed said the F-21 could be India’s pathway to the stealth F-35 fighter, which has entered US service in one of the world’s most expensive defense programs.

“The F-21 has common components and learning from Lockheed Martin’s 5th Generation F-22 and F-35 and will share a common supply chain on a variety of components,” the company said.

It said production in India would create thousands of jobs for Indian industry as well as support hundreds of US-based Lockheed Martin engineering, program management and customer support positions.

Meanwhile, European aircraft maker Airbus deliveries of its A320neo aircraft are back on track in India with fewer problems being seen with the narrowbody jet’s Pratt & Whitney engines, a senior company executive said on Wednesday.

“Pratt has informed Airbus that engine issues have come down by a factor of four in the last 12 months,” said Airbus’ India head Anand Stanley, on the sidelines of the Aero India airshow in Bengaluru.

Last month, India’s aviation safety watchdog forced airlines to make extra checks on their Airbus A320neo aircraft fitted with Pratt & Whitney engines, as part of new safety protocols after temporary grounding orders affected the planes last year.

IndiGo, India’s biggest carrier by market share, and its low-cost rival GoAir, both fly the A320neos.

The aircraft, which entered service in early 2016, boasts significant fuel efficiency benefits, but it has been plagued by teething issues with its engines that have forced Interglobe Aviation-owned IndiGo and Wadia Group-owned GoAir to regularly ground a number of the planes.

This caused a backlog in deliveries of the planes by Airbus.

IndiGo has over 60 A320neos in its fleet and is one of Airbus’ biggest global customer with over 400 more A320neo and A321neo jets on order. GoAir has about 30 A320neos in its fleet and over 100 more of the jets ordered.

Stanley said that the reliability rate on A320neo engines is now 99.6 percent and that it has retrofitted engines of about 95 percent of the A320neos in service. It expects to finish work on the remainder in the next two months. — Reuters
