This is the GDI 227 mm D28, a high-explosive submunition carrier, tube-launched, unguided, folding-fin, and spin-stabilized, ground-to-ground-rocket fired from the armored, self-propelled-artillery, M270 Multiple Launch Rocket System (MLRS). Each tactical rocket incorporates a submunition delivery warhead containing 644 D77 submunitions.

The D28 tactical and D26 practice rockets incorporate the N445 electronic-time-fuse that is remotely set and is sustained acceleration-armed and ram air-powered. Every rocket pod/container, a shipping and storage container for four rockets, also serves as an expendable launch platform. The tactical rocket is used against armored and personnel targets and supplements conventional artillery.

Each rocket weighs approximately 677 lbs (307 kg) at launch with an approximate expended weight of 463 lbs (210 kg). A fully loaded rocket pod/container weighs 5,236 lbs (2,375 kg).
