DSTA led the acquisition of the multi-role F-15SG aircraft and worked with defence partners to deliver an integrated suite of advanced sensors, avionics and weapon systems. One of the weapon systems equipped on the F-15SG is the 2,000lb Joint Direct Attack Munition (GBU-31).

The GBU-31 is a Global Positioning System-guided, fire-and-forget precision munition that allows the F-15SG to carry out precision strike missions efficiently, especially on larger targets. With the GBU-31, the F-15SG is able to eliminate multiple targets with precision and accuracy.

The air superiority of the F-15SG aircraft and enhanced firepower of the precision strike capability have been demonstrated in major RSAF exercises.
