View source for Second Submarine Flotilla (Royal Navy)

The '''Second Submarine Flotilla''' was a formation of [[Submarine|submarines]] of the [[Royal Navy]].  Created around 1904 as one of the first two formations in the R.N. for submarines, it was called the '''Portsmouth Submarine Flotilla''', also occasionally termed "Section V., Submarine Flotilla".{{NLApr11|p. 270''b''}}

==History==

When Britain first started organizing its early, coastal submarines into formations, it decided to create just two flotillas, basing them at Portsmouth and at [[Devonport Submarine Flotilla|Devonport]].  They sprang into being about 1904 or so, and involved the original, numbered boats, and soon thereafter "A", "B", "C" and even a few "D" class boats before numbers and the merit of the new weapon demanded moving to several numbered flotillas.  The Portsmouth flotilla would, in 1912 or so, become the Second Submarine Flotilla.

===April, 1911===
The flotilla is comprised of four "A" class coastal boats and a single "D" class submarine.{{NLApr11|p. 270''b''}}

===August, 1912===
The Portsmouth Submarine Flotilla is by this time designated the Second Submarine Flotilla, this change occurring perhaps around May, 1912.  Its composition has changed since our last data in April, 1911.{{NLAug12|p. 270''b''}}

The flotilla serving with the Portsmouth Defence will be keeping {{UK-Dolphin}}, {{UK-S1}} and {{UK-K3}} while picking up two other coastal submarines and the name {{UK-SF|6}}. It is not clear what has become of {{UK-B1}} and {{UK-B5}}.

Back as one of six flotillas supporting the Grand Fleet in the post-war navy, the Second has a leader, a depot ship and seven "K" class submarines.
