In a follow-up to the post on the German Type 212A submarines earlier this week, check out this SINKEX of the former Hellenic Navy transport Evros (A-415)— herself the ex-West German Navy Type 706 replenishment ship Schwarzwald (A1400)— sent to the bottom of the Agean by the Greek Papanikolis- (German Type 214)-class submarine HS Pipinos (S-121) through the use of a warshot SST-4 Mod. 0 Robbe (Seal) torpedo off Karpathos island last month.
The SST-4, introduced by Atlas Elektronik in 1980, is a Cold War-era 533mm heavyweight wire-guided/passive homing torpedo that has been replaced in German service with more modern fiber-optic guided torps. Still, it seems to work well enough to do the job against a stationary target ship, anyway.
In the video below, you can see the fish track all the way on the surface to make a near-perfect hit.
Of note, the Turks, who also operate German-made subs, had a SINKEX, two years ago, with TCG Yıldıray (S-350) using an SST-4 against a retired tanker, TCG Sadettin Gürcan (A 573)– of course putting the Greeks on notice.
