Yes but the deal was under iddm so it will be fraud if some foreign system is allowed to participate.
IDDM allows foreign participation. Only the indigenisation percentage is different for each category.
‘Buy (Indian-IDDM)’ category refers to the acquisition of products from an Indian vendor that have been indigenously designed, developed and manufactured with a minimum of 50% Indigenous Content (IC) on cost basis of the base contract price i.e. total contract price less taxes and duties.
‘Buy (Indian)’ category refers to the acquisition of products from an Indian vendor which may not have been designed and developed indigenously, having 60% IC on cost basis of the base contract price. Vendors eligible in ‘Buy (Indian-IDDM)’ category will also be permitted to participate in this category with indigenous design and a minimum of 50% IC on cost basis of the base contract price.
And...
In order to leverage the highly developed indigenous software expertise existing in the country, it is pertinent that maximum equipment should function with indigenous software (certification by the Statutory Auditor of the Bidder that the software has been developed within India) driving the desired applications while the backend software i.e. Operating Systems continues to be OEM defined. The RFI process should clearly identify availability of indigenous software for running applications on the equipment/system and its analysis should determine whether the project should mandatorily require the vendors to base applications being run on their solution (especially critical components like Fire Control System, Radars, Communications, Encryption sub systems) on indigenous software in Buy (Indian – IDDM) and Buy (Indian) cases. In case the requirement is not made mandatory, Enhanced Performance Parameters (EPP) with respect to indigenous software should be defined with commensurate credit score (as per Paragraph 14 (c) of Chapter II) in the SQRs to provide for the enhanced capability being offered.
So there's a lot of work involved in IDDM.
