Following “Naval Group's 2nd Generation Fuel Cell AIP ready to be marketed"” of October 30, 2019 I deduce that India's DRDO AIP and Naval Group's new AIP are one and the same.
The following is an update of Indian DRDO's progress on land testing a Fuel Cell AIP system (in part to retrofit on India's Naval Group (was DCNS) designed Kalvari class Scorpenes).
This just happens to be occurring at the same time as land testing of Naval Group's 2nd Generation Fuel Cell "AIP FC-2G" (in part to retrofit on Scorpenes). Scorpenes have been sold by, what is now Naval Group, to Chile, Malaysia, Brazil and India.
See Xavier Vavasseur's, Naval News update article of 31 Oct 2019 at https://www.navalnews.com/naval-news/2019/10/indias-aip-system-gets-boost-with-operation-of-land-based-prototype/
"India’s AIP System Gets Boost With Operation Of Land-Based Prototype"
"India's fuel cell-based Air Independent Propulsion (AIP) system has crossed several milestones in technology maturity, the Defence Research and Development Organisation (DRDO) has announced.
The DRDO is an agency of the Government of India, charged with the military’s research and development. India’s AIP system will eventually be fitted aboard all Kalvari-class submarines...
...As previously reported, Naval Group India engineers are already working with the DRDO for the integration of an Indian designed [?] AIP module...."
PETE COMMENT
National and organizational pride and high budget justifications are such that every part of a submarine can be claimed as locally invented/indigenous if at all plausible.
