The SZ-3a charge was also to be used for underwater demolition op to 10meter deep.
The charge holds 2.8kilo cast TNT or TNT/RDX and the booster is compressed TNT.
When it was used underwater, it was fitted with the VPZ-1 fuze and detonator No.8
For land-use it was fitted with the electric EDP-r detonator.
Rubber straps with hooks were used to fix the charge to the object.
The charge in the photo bears the text "INERTN" , which means that this was an empty trainer.
