The S-class submarines of the Royal Navy were originally designed and built during the modernisation of the submarine force in the early 1930s to meet the need for smaller boats to patrol the restricted waters of the North Sea and the Mediterranean Sea replacing the H class submarines. Due to major naval construction of the Royal Navy during the Second World War, however, the S class became the largest single group of submarines ever built for the Royal Navy; a total of 62 were constructed over a period of 15 years, with fifty of the "improved" S-class launched between 1940 and 1945.

Twelve little S-boats "go to it" like Bevin,

Starfish goes a bit too far — then there were eleven.

Eleven watchful S-boats doing fine and then

Seahorse fails to answer — so there are ten.

Ten stocky S-boats in a ragged line,

Sterlet stops and drops out — leaving us nine.

Nine plucky S-boats, all pursuing fate,

Shark is overtaken — now we are eight.

Eight sturdy S-boats, men from Hants and Devon,

Salmon now is overdue — so the number's seven.

Seven gallant S-boats, trying all their tricks,

Spearfish tries a newer one — down we come to six.

Six tireless S-boats fighting to survive,

No reply from Swordfish — so we tally five.

Five scrubby S-boats, patrolling close inshore,

Snapper takes a short cut — now we are four.

Four fearless S-boats, too far out to sea,

Sunfish bombed and scrap-heaped — we are only three.
