"The landing pad is not available at this time..."

And there tends to fuel around the Helicopter hanger so a great place to start a fire. Every sailors nightmare.

In the case of HMS Boxer, about 80 tonnes of aviation fuel, not to mention 700 tonnes of marine fuel for the gas turbines (before decommissioning, of course).
 
DHC-4 Caribou.I have model of this plane (earlier version with radials) on to-do list.

Google doesn't show many pictures of RCAF examples-does anyone know web sites or someone who has pictures showing how they were painted and marked?I would love to make it RCAF when not in UN service.

That is a photo of a RCAF Buffalo landing at Kluane lake in about 73. I didn't take that picture but was there and saw the photo taken. I flew up there in that plane as I was with the Airborne and we were on a research project with the Arctic Institute of North America for the summer
 
A lot of aluminum in these modern ships as well, melts easier than steel and doesn't handle battle damage well, as the British experience in the Falklands showed.

Most of this is actually a myth that gets repeated all too often. The Royal Navy had already made the switch to steel superstructure construction prior to the Falklands war, after experience with a fire aboard the Type 21 class frigate HMS Amazon in 1977.

That said, it wasn't aluminum that contributed to the loss of any ships during the Falklands war. Amazon's sister ship, HMS Ardent, for example, was struck by seven 1,000 lb and 500 lb bombs, and two more that did not explode. Despite significant aluminum construction, she endured the pounding rather well before finally succumbing six hours later.

The Type 42 destroyer HMS Sheffield, usually touted as the prime example for this myth, actually had a hull and superstructure that wasn't even aluminum, but entirely steel. The Type 22 frigates, including HMS Boxer in the photo, were also steel. You will note that her damage is largely from blast instead of fire.

Where aluminum does fall short of steel is in its lower fatigue life and susceptibility to deformity under high heat. It still doesn't melt, except under extreme temperatures. So lighter weight but still important fittings like aluminum ladders aboard ship would tend to fail before steel.
 
When I was in university I had a sociology prof who was a US Navy WW2 vet and said that he a had attended the US Navy fire fighting school where he was taught that anything would burn. He learned that this was true while serving aboard a ship that was hit by kamikazes off Okinawa. That was a bonus tidbit for the boys in girls in his sociology class.:sok2

Destroyers took the brunt of the losses from kamikaze attacks in WWII. An aircraft loaded with fuel and one or more high explosive bombs makes a very effective weapon against a relatively small warship, even one constructed from mild steel. You can readily see the difference between that era and the modern approach with the higher strength steels used in warships like the Arleigh Burke class, e.g. USS Cole.

Regarding aluminum, the USS Belknap's aluminum superstructure burned quite nicely in her collision with USS John F Kennedy in November 1975. Helped along in large part by aviation fuel spilling from the Kennedy, and exploding ammo from her 3 inch Mk 33 gun mounts aboard Belknap. Producing those very high temperatures. The US Navy's Littoral Combat Ships (aka Little Crappy Ships) make extensive use of aluminum.

Jet fuel can't melt steel beams. JET FUEL CAN'T MELT STEEL BEAMS! More people should have attended that class.:)

Canada's answer to the Nebelwerfer, the "Land Mattress", or Projector, Rocket 3-Inch, Number 8 Mark 1:

Looks like it took a while to load. I understand they were pretty inaccurate, as such critters tend to be, but would put a serious hate on a broad swath of the earth, and most importantly all at once. No ranging shots or quiet introductions that allow Jerry an opportunity to go to ground. Just a sudden whooshing and then your part of the planet blows up.

Want to see one? CWM has an example parked next to its old wartime German equivalent:

They should take it out from time to time and lob a salvo into the river. Canada Day, maybe, or Victoria Day.

Good eye, Shredder. A quick search of "hedgehog ASW" nets us this:

Same basic principal, just a question of range. Looks like the Hedgehog threw them pretty close to the boat:

Land mattress tossed them up to four and a half miles away...:)
