Navigational Statistics
During the 1st commission HMS Londonderry steamed approximately 78,000 miles, three times around the earth. Her screws turned over 30 million revolutions, giving an average speed of just on 14 knots for the 5,600 hours the ship will have been underway. She visited 50 ports from New York to Naples and Valparaiso to Vancouver, in 35 different countries and islands. From the commissioning date to the day of arival back in Portsmouth she spent exactly one third of her time at sea. She crossed the Atlantic four times, and went through the Panama Canal three times.

Gunnery Statistics
The ship fired 1,232 rounds of 4.5" ammunition, and 442 rounds of 40/60 ammunition at various targets, and tore large holes in the horizon when no better target offered itself.

Anti-submarine Mortar & TAS Statistics
Bill and Ben was responsible for nigh on 20,000 lbs of HE going into the water, and the Mighty Mouse below squeaked at least 40,000 times, deafening submarines of six different nationalities including the USS Nautilus.

Supply & Secretariat Statistics
128,136 eggs and 58,772 lbs of bread was eaten, and one would not dare to count the chips!

Sporting Statistics
Allegedly the ship had the best soccer, rugby, cricket, hockey, and shooting teams in the Royal Navy but I only have their words for that.
