New production Russian 3OF27 (Ru: 3ОФ27) 115 mm high explosive fin-stabilised (HE-FS) tank gun projectiles have shown a change in explosive fill
The new projectiles incorporate TA-20 in place of the original A-IX-2
The compositions are:
- TA-20 (Ru: ТА-20)
  - 80% TNT
  - 20% aluminium
- A-IX-2 (Ru: А-IX-2)
  - 73% RDX
  - 23% aluminium
  - 4% wax
This change is unlikely to significantly affect performance, but may indicate a shortage of RDX
