Names used by Air , Land and Marine Forces to name something

[tigercat]

I was looking for a name for a model I am building and decided on HMS Buffalo

It turns out as well as various HMS and USS Buffalos, there was the Brewster Buffalo and of course the

Landing Vehicle Tracked (LVT) Buffalo

so I wondered what other pieces of military tech had names common to all 3 branches of the military.

Five for starters...

Tiger  - Henschel/Porche tank, Grumman F11F & Northrop F5, HMS Tiger (18 RN ships including the WW1 battle cruiser and post-war cruiser)
Comet  - Cruiser tank, DeHavilland airliner and HMS Comet (15 RN ships ending with 2 DDs in the 30s and 40s)
Crusader - Cruiser tank, Vought F8 and 3 RN ships (all DDs)
Eagle - Desert Eagle pistol, McDD F15 and 18 RN ships (ending in 2 aircraft carriers)
Leopard - Post-war german tank family, Xian JH7 Flying Leopard and 11 RN ships (ending in the Type 41 FF)

The trick is to think of an army name first, armies dont seem to be very imaginative in naming things (M1, M2, T34, T35...), and then match to an aircraft.  Then Google HMS XXX and find out how many RN ships ther have been...

Nimrod is a good example:

Five or six Royal Navy ships have borne the name

Hawker Nimrod fighter of the interwar period

Hawker Siddely Nimrod patrol aircraft

In WWII the Hungarians had an anti aircraft tank called the Nimrod

There is also the Nimrod anti-tank missile developed by the Israelis

"Names used by Air , Land and Marine Forces to name something"

OK, this doesn't answer the question but it fits the title...

During my Reserve Officer training, we had this bigger exercise and our 120mm mortar company had to have a code name for communications... The powers that be decided to call it "Jänö". That is Finnish, and the English equivalent would be "Bunny" 

We were a bit miffed about not being called Iron or Steel, first, but then decided that it was fitting in a way: once we fired a pattern, we'd bounce to a new position that was far enough from the artillery fire soon falling on the previous position.

Scorpion - many RN ships, F-89, CVR(T) light tank.
Scimitar - multiple ships, Supermarine naval fighter, another CVR(T) variant.
Valiant - many ships (RN, USN, USCG, etc), two Vickers bombers, Vultee trainer, appalling WWII tank design.

Comrades, let us not forget Katyusha!

Katyusha class submarines from 1938, Katyusha rocket artillery and the Tupolev SB Katyusha bomber
