I hope its the latter. Hopefully, Solar Industries which received TOT from the TBRL.https://solargroup.com/wp-content/uploa ... /MMHG1.pdf
OFB had issues absorbing MMG tech (no surprise) and it was under modification in 2010-11. The orders above placed in 2010-11 were on "hold" (the 10 Lakh order, only 35,000 were produced, 18 Lakh order is a mistaken report) as Army wanted a time delay of 3.5 to 4.5 seconds on throwing the grenade, whereas the fuze was averaging 2-5 seconds in practice.
So the TBRL was looking for private partners to continue the project & MODs stance was that the limited time envisaged by the IA was not feasible either (implying then imports probably had similar performance). So, in essence, this 10 Lakh unit order is likely the older one dusted off and put back on the shelf.
Meanwhile OFB continued tinkering with the M36 design detonator, coming up with.
Detonator 36m Grenade 4 Sec Delay
So where are we today?
The Solar Industry PDF clearly indicates 3.5 - 4.5 seconds, indicating
that the issues were likely resolved.
So lets go back to what DRDO states as of 2017.https://www.drdo.gov.in/drdo/pub/techfo ... 17_WEB.pdf
TBRL has developed a multi-mode hand grenade as a potential replacement of 36 M grenade. It uses preformed cylindrical mild steel fragments to achieve uniform distribution. After successful development of multi-mode hand grenade,ToT has been done with OFB and private industry. Production has been established in the premises of private sector ToT holder and 2000 nos. have been produced for user’s trials. DRDO internal trials from the production lot has been completed, which meets all GSQR requirements.
Time delay 3 sec and arming delay of 0.5 sec provides additional safety to the thrower
Hence the renewed 10 Lakh unit order & my bet is it is Solar Industries, hence the lack of any "who makes it information" in the news report so our great OFB unions dont throw a fit.
