With the reorganization of the Aequatian Military's Naval Combat Arm, a void appeared where a missile delivery vessel was needed. Now two designs have been submitted for approval and prototypes have been constructed, however the people in charge are having trouble choosing which design to give funding to.

The Phalanx system is a bit unreliable, at least compared to what could replace it, if you can spare the space upgrading to a Goalkeeper CIWS would be advisable.

I was considering the 30mm Goalkeeper CIWS for all of my Navy's vessels in the coming future.

I would say the nuclear cruiser because it can travel indefinitely... But I'll say the gas turbine cruiser due to the fact that it is faster and undoubtedly cheaper...

If I was to make a decision, I would go with the Excalibur class CGN, unless I wanted to avoid nuclear use. It has superior range with it's nuclear powerplant, of course, at the sake of reduced redundancy. It's main guns are superior to the 3'' of the Defiant, since I tend to look for fire support capability in my own ships this makes the Excalibur better than the Defiant. The Excalibur also features the Harpoon ASM cells, which could reduce the need for ASW platforms in your task forces.

The advantages of the Defiant lie in it's faster speed (do you have the tactical circumference for the ship, or in otherwords how long it takes it to go from say a heading of North to South), and it's redundancy (4 boilers mean if one goes out, it keeps going, the Excalibur can not afford even one loss. But I still think the Excalibur is a superior ship.

I purpose-designed the cruisers to be a mobile missile platform, but I'm not sure if it would be good to have them always on the move and ready for action or always on alert and quick to deploy.

Doujin has worked extensively on improving reactor design for it's warships. Our reactors literally recycle the fuel they use, thererfor it is much more cost effective.

Many ships in the Doujin Navy abandon the traditional "screw" propellor design, in favor waterjet systems.

That depends, actually. It depends on natural gas/oil prices, then you need to crew a whole new ship to refuel it, and there are many other factors. *shrug*

Also, I would like to note the A4W Presurized Reactor is a terribly inefficient and, most importantly, a really old design. :)

I didn't know it was inefficient or an old design, it just seems like the cheapest to use and most common.

BTW, Aequatio how much were you going to pay for each one?

Cause you can always find ships produced by other countries, such as my Wang Anshi Class Guided Missile Cruiser (http://s6.invisionfree.com/International_Mall/index.php?showtopic=162).

I hadn't figured out prices, since I have yet to include the electronic equipment and suites that will be outfitted.

Hey, if this is going to turn into an advertisement campaign, you could always buy the Centaur Class Mk.2 Guided Missile Destroyer (http://www.gaizme.com/nationstates/index.php?name=PNphpBB2&file=viewtopic&t=15&start=0&postdays=0&postorder=asc&highlight=) (It's Cruiser size but it lacks so command and control capabilities therefor we classify it as a destroyer).

But I think he's trying to design his own thing.. therefor advertising isn't really nice..

Bloddy difficult one this:
they both fufil the primary role equally well the only main differance is that one is nuclear with heavier anti shipping/fire support hitting power while the other is faster, conventional and slightly better at AA work due to the rapid fire gun (while 76mm super rapid isn't brill for AA work, it is still soemwhat useful).

Since neither of them would really be able to offer much in terms of survivability when in the rnage to carry out shore bombardment i would say go for the Defiant, it is likely cheaper and less likely to be persaded into doing anything other than it's job.

Of course the Crookfur way would be to take the defiant, reduce the speed, repalce the 76mm gun with a 155mm, the CIWS with 35mm millenium guns, and the seawolf with ASTER15 but thats just me taking my pick from random suepr duper vaguely Rls tuff so proabably not what youa re looking for... so i restate my advaice go with the defiant.

Enough with the shameless plugs in my thread, I asked for advice not other nation's ships to buy. >.<

After careful consideration, the Admiralty has decided to adapt the Excalibur Class Guided-Missile Cruiser as the Aequatian Navy's premier marine missile platform and fill a new role of medium surface combat vessel should the need arise. A total of fourteen cruisers of the Excalibur class will be constructed for service, as for the Defiant class, it shall either enter service on its own or sold to a foreign navy.

The Dominion of Kotterdam would like to inquire as to the possibility of acquiring the rights to the Defiant-class design for production and use within our own navy. It seems like an excellent base on which to begin our CGX project. We would be more than willing to make whatever monetary compensation you may require in exchange for this vessel.

While we did not adapt the Defiant as our main cruiser, we must decline to release its production rights. We can however provide you with as many vessels required so long as you pay for the production costs.

Unfortunately, this arrangement would not be sufficient to our needs. The Defiant does not quite meet our CGX requirements, but it comes close enough that the integration of certain proprietary Dominion technologies and systems would bring her up to standard. We wish you the best on your foreign naval sales, however.

Well Crookfur would be interested in the Defiant but... we would onloy want the hulls and engines as the rest of our stuff is pretty much home grown (or bought from UE).

If you could asupply us with 30-50 bare bones vessels we would be willing to use them as interim missile criusers.

Our shipyards can produce the vessels with base structures, cost will be calculated once the price of the vessel can be figured.

Many thanks, the blank check is wired.
