Thur. May 24, 3049: The DCMS Procurement Department announced the commission of another Lysander Carrier Submarine.

underwater mech fights, we need this, with zero g mech fights and no atmo mech fights on moons.

The Lysander-class Carrier Submarine was a creation of the Draconis Combine during the late 3040s by the order of Theodore Kurita. The carrier was created due to the difficulties the Combine encountered on oceanic worlds during the War of 3039. The Lysander was designed to provide a substantial presence at sea and a mobile base for Aerospace Fighter craft for defense against orbital threats, submerging to protect both itself and its aerospace assets from orbital fire. Due to the ship's size, each Lysander must be built on-site on an oceanic world.

[Storm McIntyre]

The Lysander is a good force projection vessel and an excellent aerospace fighter platform on water dominated worlds. I would dare say also they would make an excellent command base for planetary defensive operations during a planetary assault.

In short, assaulting a water dominated world in the Combine is about to become an order of magnitude more difficult.

[PurpleBullet]

Oh yea that would be sweet 0g space battles

[TheFreeman]

Totally agreed with wwiiogre. A "space" map and an "underwater" or "half-underwater" map would be great!

This is what it looks like:

[Randalf Yorgen]

actually no it doesn't, there is a picture posted much further down the thread. This looks like the US Sub that first tested submarine launched ICBMs although it could be the Japanese sub that carried a scout plane in WWII.

That's the WW2 Japanese Sen Toku/I-400 type submarine actually. Largest real submarine aircraft carrier, as far as I know. I figured it would be of interest as the progenitor of Lysander.

well, unless you are going with an energy only loadout (even they have reduced ranges) you would have to use the underwater rules which include removing LRM/SRM systems and replacing them with Torpedoes. What's more, only mechs with ejection pods should be used unless you wanted to eject underwater, which wouldn't end well. It would be fun, but maybe only in Hard Core matches where your character could actually die and you would have to roll a new one. Could be for special events maybe.

(a Mech walking underwater)

[Pilot] "This is Bravo 2, I am engaging hostiles!"

*fires medium laser*

[Pilot] "Arg! I can't see anything! There's so much steam!"

*fires AC/5*

[Pilot] "Oh ****, my AC rounds are just fragmenting as they leave the barrel!"

*fires PPC*

*WHOOOOSH*

[Pilot] " ******* **** STEAM CLOUD AGAIN!"

*fires zee special underwater misles*

[Pilot] "Finally, something that works! Fish away!"



Underwater battles would be dominated by highly-manuverable guided torpedoes that you couldn't evade... and Mech-sized Harpoon guns that would replace ballistic and energy weapons. They could use large harpoon darts for fighting Mechs and small harpoon darts for intercepting torpedoes, but I don't think Mech Harpoons are canon...

I thought of that after I posted and have corrected my original post. Good catch on your part though, tip of the hat. ;D

[Kenyon Burguess]

subs would be a neat addition. compartment flooding and drowning when ejecting could be interesting twists

[Skylarr]

There is an Urban Legend about a unit trying to travel under water to hit a target. They were intercept by a submarine. Mechs have limited range underwater. The Sub used torpedoes.

They have Harpoon SRM Specialty ammo, but I don't think that's what you're thinking about...
LRTs and SRTs are about as manuveurable as LRMs and SRMs from what I gather. In the future, high explosive, wire-guided, 10000+ foot-ranged torpedos are replaced by kinda lame-explosive, almost ballistic (AKA: non-guided), 640-foot ranged missles-with-propellers.

[Sprouticus]

As anyone who has actually served on a sub can tell you, you dont HAVE to direclty hit a target to destory it or severely damage it. In reality a near miss is good enough. (think depth charges from the old WW II movies).

Water is DENSE compared to air, and concussive force does not disipate quickly like it does in air.

That is why US subs only have a couple of pressure hatches. The reality is that if you get fired upon and a near miss is bad enough to cause flooding, you are dead.

Armaments & Capacities

The Lysander is designed to carry four squadrons of Aerospace-type aircraft which act as the ship's principle offensive weapon. Usually, a Lysander will carry three fighter-type aircraft squadrons and a single VTOL squadron. Aircraft are stored in thirty fighters bays while take-off/landing is provided for by a flight deck and four helipads.

Weapons on the Lysander includes eight ER Large Lasers on single-turret mounts with six ER Medium Lasers. Mounted in the ship's bow are four additional ER Larger Lasers, four Twenty-tube Long-Range Torpedoes Launchers, and four Six-tube Short-Range Torpedo launchers. Another four rear-firing Six-tube Short-Range Torpedo launchers are mounted in the aft section. For artillery support, the ship carries eight box-launched Arrow IV launchers. The total amount of ammunition stored on the ship includes forty Arrow IV missiles, eight tons of SR Torpedoes and four tons of LRM-20 missiles. All of the ship's weapons are guided by an Advance Fire Control system.
The ship is protected by 1,389 tons of Standard Armor and receives additional protection from a Guardian ECM. Other features include two field kitchens, a MASH unit, Communications Equipment and thirty lifeboats. Accommodations include two hundred crew quarters and forty second-class passenger quarters.
In addition to its fighter compliment, infantry detachments are sometimes assigned to the ship.
Cargo

The ship carries 2,549 tons of standard cargo, which used to supply the ship on long voyages and sustain is aerospace compliment.
The ship has three Heavy Vehicle Bays (100 Tons each) with doors mounted in the rear of the ship.

Armament

• 12 x ER Large Lasers
  
• 6 x ER Medium Lasers
  
• 4 x LR Torpedo 20s
  
• 8 x SR Torpedo 6s
  
• 8 x Arrow IV Launchers

Heat Sinks 174

Crew

• 26 Officers
  
• 70 Enlisted/Non-Rates
  
• 106 Gunners
  
• 60 Bay personnel

Long-Range Torpedoes (LRTs) have provided ocean-going military units with a decent far-reaching punch for centuries. The LRT-20 fires twenty such torpedoes at an enemy.
Short-Range Torpedoes pack more power into the missile than almost any other kind. They lack sophisticated guidance systems, so they must deliver their punch at short range. The SRT-6 fires six such missiles at a time.
Though the SRT-6 is a modified version of the SRM-6, it cannot fire the same special munitions.
Squadron
Typical Inner Sphere formation consisting of 6 units or airborne vehicles. Consisting of 3 flights. This does not include a Command Flight for the unit's commanding officer.

Except.. Draconis squadrons organise as flights of 4 with three such four unit flights.

If you look around you might find a posted photo of a Model of a Sea Wolf class sub with a cylindrical container abaft the sail large enough for the STOVL F35 Naval variant (with folding wings). It's a think tank sort of concept, but still a direct descendant of the French Surcouf, German Typ XIB (never launched), the Japanese "B" class fleet submarine, and, of course, the spectacular I--400 class. Frankly, I had thought the idea had been superseded when the sub--launched Harpoon and Tomahawk were introduced, but, upon reflection, I see that there are some missions a manned aircraft can perform that a guided missile cannot.

[Insidious Johnson]

cool thing that it is, its no submersible drop ship and is only built on site. Withdrawal is not an option.
