ORP Orkan (ex HMS Myrmidon) was one of 16 builded destroyer L/M class, one of 8-ship M-series, but her service made this unit unique:
- Ship was transferred straight from british dockyard to Polish Navy,
- In WW II was most advanced and modern destroyer, used by Polish Navy,
- After the 1943 Gibraltar Liberator crash (in this tragedy died commander-in-chief of the Polish Army and Prime Minister of the Polish government-in-exile - General Władysław Sikorski) Orkan carried coffin with General’s body from Gibraltar to Plymouth in England,
- Torpedoed in Notrh Atlancic in 8 October 1943 and sunk with 178 polish and about 20 british seamens - almost 3/4 crew died in icy water. Only 44 peoples was saved,
- One of first victim of german acoustic torepedo - T5 Zaunkönig (wren).
Beside this, L/M class destroyers are absent in GB naval tech tree and this ship with unique and tragic history is original representative of own class in GB Navy.
