Sorry, that's not what I meant. I wished that the new ships they were planning to buy from us had our sensor suitesIn other words, all of the private shipyards (moreover the subcontractors who do most of the design work) has gained the knowledge during milgem programme (which is still ongoing). Any development occuring nowadays owe it to past 20 years.
I am not sure if it will be an upgrade. The ships is old and has been inoperational for last few years. Given the time and availability of documents (How nicely Nigerian Navy archiving) this will be morelikely a life extension refit. At this stage it makes more sense to buy a new ship than upgrading all those analogue systems and cabling altogether.
