Only Sig (junge1) went closer to the solution: but it isn't a missile silo. In fact it's the interior of a torpedo launch tube of the submarine HMCS Onondaga, in Rimouski, Quebec. It's been taken from the opening. Here you can see the same shot taken with a tele, zeroing in a buoy.The light at the end of the tube is similar to that they say one sees when is dying .... in this case after being torpedoed! I put three clues, but the most important one was utterly disregarded. It was hidden in open view, in the photo specifications at Genre: Military. So none of you is a spy or a detective. ;D) I'm going to post more images of this old veteran girl. So I'll start her remarkable story here: HMCS Onondaga(S73) is an Oberon-class submarine that served in the Royal Canadian Navy and later the Canadian Forces.It's the longest serving submarine in the Canadian Navy, now at the Musee de la Mer de Pointe-au-Pere in Rimouski, Quebec. Onondaga was laid down on 18 June 1964 at Chatham Dockyard, Chatham, UK and launched on 25 September 1965. She was commissioned into the RCN on 22 June 1967 with pennant number 73. She was decommissioned by Maritime Command on 28 July 2000 as the last CF Oberon class submarine in operation. Onondaga was assigned to Maritime Forces Atlantic (MARLANT) and served her entire career in the North Atlantic. After narrowly avoiding being sold for scrap, the Onondaga was sold to the museum for $4 Canadian plus tax. The submarine has been restored for a reported $2.6 million, and opened to the public in May 2009. The Onondaga was towed from Halifax to Rimouski by way of the Canso Canal in July 2008. The tow was featured in the reality TV show, “Monster Moves.” Badge: Blazon Azure, within a representation of the wampum of the Iroquois nation, another of the head of the mace used at the sitting of the first Parliament of Upper Canada in 1792, both proper.
