The Boeing fighter jet is vying for an Indian Navy contract and that service only has aircraft carriers with ski jumps at present.

This's one of the articles that talk on India interest for Shornet also related to potential of finding Aircraft that can work both in STOBAR and CATOBAR.
Basically Mig 29K is build for STOBAR as Super Hornet build for CATOBAR. What Boeing want to shown is the application of Shornet in STOBAR environment too. If India next carrier will be CATOBAR, then it's going to be difficult for Mig 29K to catch up. Considering Russia has so far shown no development toward catapult launch system. Thus I think it will be difficult for Russia to develop their Fighter toward catapult launch application, as they don't have facilities on that.
Seems SAAB effort to build Navalised Gripen also aim for STOBAR (forgot the article that shown SAAB Navalised concept). They will also I believe will found challenge to provide Navalised Gripen than can work in both STOBAR and CATOBAR environment.
All this's due to specialise facilities of CATOBAR testing. I don't think US will open their facilities for MIG and SAAB to develop CATOBAR capabilities. Unless they can work with China or French. Long shot on that considering French also working on the similar deal for Navalised Rafale.
