Yes, that's how Indian R&D goes. There can be defects on items, changes in requirement or even failure that they don't go public.Even if those 15 units were for Dev/User trails, yet quite a lot of time has passed now and LSP won't be that far off.
This tweet was made in Apr. 30, 2023 and now we're almost reaching April 2024. So literally one year has passed from the time of the tweet.
For example, I was following the NPOL ALTAS sonar program since 2012. It underwent user trials after placing orders with MSMEs like Keltron. The last news we heard about it was in 2019 when NPOL requested EoI from industry partners. Then suddenly, a CAG report revealed the project's closure last year.
Or How many times has the NAG been declared a success? And where is it now?
Don't be certain about things in development. You will never know.
