Talk:HMS M2 (1918)

The photy is about Peto retrieving, not launch. There was no need to use crane to launch the aircraft, and the aircraft was already on catapult rail when it was in the hangar. Also check on this video: --Il palazzo (talk) 21:38, 17 February 2009 (UTC)

Role
I've removed this:

"they were designed to operate as part of the main fleet of battleships and so needed to be fast"

and this:

"The maximum speed on the surface was 15.5kn, which proved to be slower than the newer battleships and the concept of fleet submarines was soon scrapped, with the River class of submarines being the last"

AFAIK the M-class weren't intended as Fleet submarines; their speed was about average for submarines of the time, nowhere near the 24 knots required. But the big gun fitted equipped them as monitors or raiding cruisers; so their successor was HMS X1, not the River class. Xyl 54 (talk) 03:16, 29 September 2009 (UTC)

Launch Procedure
This is unclear: "[...] to conserve compressed air compressors were then started to completely clear the ballast tanks of water by blowing air into them. This could take as long as 15 minutes to complete. The normal procedure for launching the aircraft was therefore to hold the boat on the surface using the hydroplanes whilst the hangar door was opened and the aircraft launched."

What I believe this means is that air for clearing the tanks was stored in compressed air canisters and that the canisters were conserved by clearing the tanks directly with the compressor. I assume the hydroplane method involves the forward motion of the boat. Someone who knows for sure can clarify. 70.225.161.132 (talk) 04:54, 31 March 2011 (UTC)
