The operational stockpile of the Fragmentation Hand Grenade SFG87 was not fully consumed during the Army’s training exercises.

DSTA, along with the SAF Ammunition Command and a local defence industry partner, conducted a front-end study to determine the possibility of extending the life of the operational stockpile via a cost-effective method. Through the study, the DSTA team identified that the grenade body has a shelf life that is one and a half times longer than the fuze assembly.

Next, a feasibility study was conducted to ascertain that the process to remove and replace the existing fuze assembly is safe. The team oversaw the necessary qualifications and factory acceptance tests to verify that the changed-out grenade could still meet the performance and safety requirements.

The team’s efforts led to the successful change-out of the fuze assembly, extending the lifespan of the existing stockpile by 11years. This allows the grenades to be consumed through training without incurring any disposal cost and avoided further costs from the subsequent purchase of new stocks. The team’s innovation achieved a one-time cost savings of about S$5.96 million.
