Identify that Tank/Ship/Plane/Artillery etc

[Abdülmecid I]

There was only one, Royal Louis, as the construction of the rest was cancelled due to unacceptably high costs. Good job and your turn!

This is what I meant.
According to the linked article there were three 18th century French first rate ships of the line to have this name.
The French would give this name to their biggest ship, ergo my guessing of the name but not of the ship.

well, Montagne is mountain.

Correct, your turn.

Something interesting...... apart from the vessel, what are we looking at?

The torpedo tube?

[Spear Dog]

No, that'd be too easy. (...although, without giving too much away - it did in part sort of acquire a 'nickname' along those lines).

*Also, don't dismiss the vessel, it has historical significance.

[Spear Dog]

clue: this is a historically important and significant submarine.

[paleologos]

I don't get it, are we supposed to give the name of the ship, or something else?

[Spear Dog]

Sorry if this was confusing, name the vessel and identify the weapons system shown. Although you could have one without the other the simplest solution is to identify the submarine. The weapons system was a solution to a short lived conundrum and only existed for about twenty years, but was differently developed and deployed as coastal batteries, in warships and army ordinance during that time.

The submarine, as I have stated, is of significant historical importance.

[paleologos]

The ship is the Holland, first successful "modern" submarine in US service and -from what I've read- the weapon is a pressurized air cannon.

[Spear Dog]

Yes, the USS Holland, the first submarine commissioned by the US - designated SS-1. The pneumatic gun is called a dynamite gun. Pneumatic guns were the solution to using the new high explosive dynamite as a weapon. Dynamite was a stable form of the high explosive nitroglycerine for mining/engineering, but was still dangerously unstable under the high heat and high pressure of a conventional cannon. Various forms of dynamite guns were developed for use, as mentioned, as shore batteries, naval guns and field guns. They were only around for about 20 years before high explosive was developed for use in conventional weapons. As might be expected, they lacked range and velocity. *The projectile was called an aerial torpedo - a misnomer as a torpedo is specifically/originally a naval mine.

The Holland has a particular place in history besides being the USA's first submarine. The Holland is named for the man who designed and built her, John Philip Holland. His original company, The Torpedo Boat Company, was reformed at Lewis Nixon's Crescent Shipyard in New Jersey and founded as the Electric Boat Company by Isaac Rice in 1899, for this project. Ringing any bells, anyone? The Electric Boat Company went on to sell later developments of this submarine internationally. In 1952 the Electric Boat Company was reconfigured as General Dynamics Corporation. As such the USS Holland marks the beginnings of one of the biggest players (and perhaps even the origin) of the USA's 'military industrial' complex.
