Vanguard Class SSN (Flight II)

The Flight II Vanguard Class SSN is a significant upgrade on an already powerful design capable of providing an extremely powerful general purpose punch. The vessel is equipped with large calibre torpedo tubes capable of firing torpedos powerful enough to damage even the largest of vessels, as well as deploying mines and Unmanned Submersible Vehicles (USVs). The torpedo tubes are primarily intended to be used in the anti-submarine role.

The second main armament of the Vanguard is a large 64 cell VLS system running down the length of the submarine which provides the vessel's primary anti-shipping and cruise missile armament. These allow the vessel to strike the enemy navy from beyond the range of quick response, and also to launch cruise missiles. All weapons launched from the VLS tubes can be fired beneath the surface, allowing the vessel to avoid direct detection whilst firing ordnance and then quickly leave the scene.

The vessel is also equipped with two CIWS units for protection against missile threats whilst surfaced and is equipped with a powerful electronics suite, including radar, IR and visual sensors digitally linked to the submarine and mounted on a periscope which can feed information to both the crew and weapons systems without the submarine having to surface.

The vessel is propelled by an extremely quiet waterjet connected to a nuclear reactor. The reactor allows the vessels to remain at sea for extremely long periods without refuel. A Combined Gas And Diesel turbine is also provided as a backup powersource in the event that the nuclear plant is taken offline or has to be shut down.

The vessel is constructed from amorphorous steel, which is both a very strong material and excellent for submarine construction, being completely non-magnetic. The vessel's strong double-hull allows it to reach previously untouchable depths, providing it with a significant advantage when evading enemy detection and enemy anti-submarine fire.

[OOC: In case anyone's interested, the first (and so far only) squadron to be equipped with these is the 1st 'Guards' Squadron I've deployed in the Velkya thing - http://forums.jolt.co.uk/showthread.php?t=455610 ]

OOC: Nice.

*bump*

Nice.

When are you going to reopen IPS?

[OOC: When I've done a couple more new ships and stuff.]

The Democratic Imperium is pleased to see a fine new design coming out of IPS once again, and would be more than happy to acquire some of these new SSNs. However, we are already in possession of some one hundred Vanguard-class vessels. We would therefore like to inquire as to the possibility of sending these vessels to IPS for upgrading to the Flight II specifications.

Dear Sir,

We would be willing to upgrade any Flight I Vanguard Class submarines you have in service in IPS shipyards to the full domestic standard for a total of $200,000,000 ($200 million) per submarine. The work can be done on twenty boats simultaneously, although we can accomodate more if you are in a hurry to receive updated boats. I hope that you find this satisfactory.

Yours,

Sir Gallius Flavus,
Director-General of Imperial Praetonian Shipyards

The IMN also operates several of these attack boats. Would it be possible for us to have the same procedure carried out at your shipyards?

Indeed.

Excellent.

The Velkyan Navy, and in particular, the Submarine Fleet Posideon, will purchase 20 of these boats.

50 billion wired upon completion.

Dear Sir,

I am happy to be able to supply your navy with the requested 20 boats, and I hope that they will greatly aid you in the defence of your nation, especially in light of recent events. The boats will take an estimated 4 years to complete in full, and will be delivered to your nation at that time. I hope that you take an interest in IPS products again in future.

Yours,

Sir Gallius Flavus,
Director-General of Imperial Praetonian Shipyards

not my particular naval preference, but good sub.

damn nice design.
(ooc: argh, that thing would kick every sub in my fleet's arse! thats my PMT fleet too, worse luck. someone found my big-arse weak-point. remind me not to annoy you, although my MT surface craft would'nt be too horribly vulnerable to it mind...)

The Imperial Chief of the Maritime Forces (Think the Navy and the Army combined, with the Army acting as a huge Marine force with amphibiously deployed artillary, tanks and all the rest an Army has.) requests in the name of his Holiness, the Holy Emperor of MelekTaus, that 20 of these ships be constructed. In his magesty's name, you may take the required funds from our cut of the Defense Budget, which including the Home Fleet, Home Maritime Army and Airforce (Plus Auxillairy Airforce) totals $1,227,299,501,008.00

We are indeed in a hurry to acquire the Flight II upgrades as soon as possible. We will pay an additional cost of whatever you wish, in addition to the $200 million upgrade cost, to accommodate the extra load on the shipyards. Alternatively, perhaps we can work out some sort of system whereby the upgrades could be carried out at our own shipyards?

Prae, when are you going to reopen IPS?

Prae, when are you going to reopen IPS?

I asked him that on the first page of this thread.

The Velkyan Naval Shipyards at Vladistock would like to ask if there are production rights, and if so, how much?

bump

MelekTaus - Dear Sir,

I am happy to be able to confirm your order for 20 submarines, which will take a total of 5 years to complete. I hope that the vessels will serve your navy and nation well, and that you will consider purchasing future units as additional capabilities become necessary and affordable.

Yours,

Sir Gallius Flavus,
Director-General of Imperial Praetonian Shipyards

Halberdgardia - Dear Sir,

In that case we can have all of your submarines completed within 2 years, with every submarine in refit at the same time for exactly the same cost. This will, however, mean that for those 2 years your navy will have no Vanguard Class vessels at all at its disposal.

With regards to completing submarine upgrades in your own shipyards - this would certainly be possible, however it would most likely only increase the costs as components would have to be sourced from Praetonia, and IPS engineers would have to be hired either to conduct the refits, or to train your own engineers in how to do so.

Yours,

Sir Gallius Flavus,
Director-General of Imperial Praetonian Shipyards

Southeastasia - As I said earlier in the thread, when Ive done some more new ships and I feel I have enough to warrant reopening it. Probably two weeks or so before Christmas.

OOC: I know, I know. After reading McKagan's post, then seeing the first page, I got that.
