RFP to Honey­well for Jaguar re-en­gine this month


The Min­istry of De­fence (MoD) is ex­pected to send out an RFP to Honey­well this month for the F125 IN tur­bo­fan en­gine for the IAF’s Jaguar fleet, IAF Chief Air Chief Mar­shal N.A.K. Browne has re­vealed. The F125 IN en­gine emerged last year as the only suit­able pow­er­plant to re-en­gine the Jaguar and re­place its Roll­sRoyce Adour Mk811 tur­bo­fans.

In Fe­bru­ary last year, Rolls-Royce pulled out of a two-way com­pe­ti­tion af­ter the IAF in­sisted that the com­pe­ti­tion was to re­place the Jaguar’s en­gines and not merely up­grade them. Rolls-Royce had of­fered (and in­deed, con­tin­ues to of­fer) a com­pre­hen­sive ‘low-risk op­ti­mised’ up­grade in­volv­ing the Adour Mk821 en­gine. Sources in­di­cate that the Honey­well en­gine had an edge from the start, con­sid­er­ing it was lighter and had proven to re­quire less mod­i­fi­ca­tions for in­te­gra­tion. Last year, it had been con­jec­tured that the com­pe­ti­tion would be re­floated. How­ever, af­ter a study found that no en­gines in the global mar­ket would suit the Jaguar other than the two that com­peted, the IAF rec­om­mended that it would go with the Honey­well of­fer­ing, as a di­rect pur­chase.

The F125 af­ter-burn­ing ver­sion pow­ers the Tai­wan In­dige­nous De­fense Fighter and the non-af­ter­burn­ing ver­sion, the F124, pow­ers the Czech fighter and the M346. “As an ‘off-the-shelf’ en­gine so­lu­tion, the F125IN is de­signed to drop-fit into ex­ist­ing Jaguar air­frames, re­sult­ing in an en­hanced air­craft with su­pe­rior mis­sion ca­pa­bil­i­ties, im­proved pi­lot safety, and out­stand­ing re­li­a­bil­ity, with a pro­jected life-cy­cle sav­ings of over ` 7,000 crore. F125IN will trans­form the IAF Jaguar and power In­dia into the fu­ture,” says Honey­well.
