Type 81 Cavalier-class Destroyer

http://img.photobucket.com/albums/v387/Praetonia/CavalierclassDD-Final.png

History: As part of the Year 335[PRP] Construction Programme, a competition was begun for the Future Standard Destroyer, a specification intended to provide the future general purpose escort for the Imperial Navy, primarily for the purpose of providing fleet and theatre air defence, but also for providing anti-submarine and surface warfare capability. The competition was won by Randolph Maritime Defence Engineering Ltd.'s Cavalier-class and a War Office contract was issued to seven seperate naval constructors to deliver units from several hundred shipyards. The last Type 81 unit, PWS Royal George, was commissioned into the navy in the presence of His Majesty in celebration of His Silver Jubilee following the traditional Fleet Review.

Now that production for the Praetonian navy is complete, the ship is being offered for sale by the contracted yards to foreign powers.

Overview: The Type 81 represents Praetonian maritime engineering's attempt to create a premier general purpose destroyer. The ship mounts the most capable RADAR developed for an IPN escort, a dual S and X band phased array in an enclosed mast mounted just aft of the bridge, capable of detecting and tracking targets at long range. Unlike contemporary Questerian and Willinkian destroyers, this set-up provides continual 360deg coverage with both the Volume Search S band and Multi-Function X band radars.

The system is responsible for surface search and tracking, air search and tracking, close-in defence against missiles, satellite communications, aircraft control, target illumination and electronic warfare. This sensor system is the centrepiece of the Cavalier's capabilities and represents a significant improvement in IPN information gathering capabilities.

Supplementing this system are a number of secondary antenna for communications and aircraft control and two major electronic warfare antennae. The ship is equipped with a dual band bow sonar and outfitted to receive a towed array sonar for long range search and tracking of submarine targets.

The vessel's primary armament consists of a two VLS arrays, a 100-cell array mounted on the forecastle and a smaller 36 cell system mounted aft behind the hangar. This system can receive SAMs, SSMs, ASROCs or land-attack missiles. Gun CIWS have been entirely abandoned in favour of eight-packed light missiles stored alongside normal ammunition in regular VLS cells. Just aft of the forward VLS array are two four-cell canister blocks that are used to carry SSMs in Praetonian service, freeing up deep VLS cells for SAMs.

The ship's gun armament consists of two 4.5" rapid fire Joint Littoral Gun systems, one mounted on the forecastle and the other positioned aft on a reinforced mount above the hangar. The system is fired and reloaded automatically at a rate of up to 200 rounds per minute. With a dual ammunition feed, it either fires a 22kg "High Charge" direct fire munition for use against land targets and littoral boats, or a 28kg "Low Charge" mortar round for use in the torpedo defence role. 500 rounds are carried for each weapon.

The ship is equipped with two torpedo tubes mounted below the waterline fore, primarily for the purposes of deploying naval mines but with a secondary use in ASW and torpedo defence if suitably equipped. In addition to its own armament, each Type 81 can maintain two medium or one heavy helicopter in its hangaring facilities, used in Praetonian service in the anti-submarine warfare role.

Official Communique to Praetonia

We have a pressing need to replace our destroyer fleet, which consists of 9 capture Lerasian destroyers, roughly comparable to the Fletcher class destroyers, though they have been upgraded since they entered our fleet. We have other various destroyers, though we hope with this order to have a standard class of destroyer in our naval fleet. With that intention in mind, we wish to order 125 Type 81 Cavalier destroyers for the total sum of 250 billion Universal Standard Orders.

We will wire the money to your accounts when the order is confirmed,

Signed,

Thomas Gates
Secretary of the Navy

From Grand Admiral Ryu Yamamoto of The Imperial Ryou Navy.

The Imperial Navy wishes to buy 40 Type 81 Cavalier destroyers, we ill send a Envoy to talk about The total Price you want for all the Destroyers.

can it be powered by green fuels and or nuclear?

Official Statement of the Free Republic of Kahanistan

The Government of Kahanistan wishes to protect its new economic infrastructure at home, and towards that aim, we desire to obtain 60 examples of the Praetonian premier destroyer for $120 billion USD.

We believe it suits our needs more than our surviving fleet of nuclear-powered destroyers for short-range homeland defence.

Signed,
Fleet Admiral Carl Jenkins,
Commander of Naval Operations,
Kahanistan Republic Navy

Logan and Ky wishes to purchase 350 of these ships for the price of 700 Billion USD. Money will be wired upon confirmation.

The Commonwealth of Tolvan would like to purchase forty-five (45) Type 81 destroyers to replace our aging Type 30 class destroyers and supplement our Type 38 class destroyers. However, we request pemission to replace the 4.5" Joint Littoral Gun System mounts with the Commonwealth Gunnery Systems Mk. 48 135mm gun mount. We are prepared to pay an additional $50 million per ship for this modification for a contract total of $92,250,000 to be wired upon confirmation of our order.

These modified vessels will be known as the Type 44 in Tolvanic service.

FROM THE OFFICE OF THE MINISTER OF THE MILITARY
ON BEHALF OF THE IMPERIAL NAVY
GRAND ADMIRAL JAMES E. ROCKENBACH
The Shazbotdom Imperial Navy would like tou purchase 400 of these fine vessels for use in the Shazbotdom Imperial Navy with a total price to come out to $800,000,000,000. Payment will be made upon acceptance of our order.

We would also advise against the selling of these vessels to The Ryou Black Islands as they are beginning to show signs of early warmongering.

[OOC: I think orders are generally SIC. Then again, warning against sale to Ryou may be standard operating procedure for the Shazbot Navy, or you may have intel I don't know about. I'm making an issue here because once last year my purchase of a huge fleet was used as evidence I was preparing for war.

Then again, we'll probably be waiting a while for responses anyway - I've waited nearly a month. Consider this a GLORIFIED BUMP.]

The following vessel order contracts have been signed:

Calizorinstan - 125 hulls
Kahanistan - 60 hulls
Logan and Ky - 350 hulls
Tolvan - 45 hulls; front mount can be replaced but the aft mount cannot take the additional weight
Shazbotdom - 400 hulls

The Ryou Black Islands should be aware that the price of the destroyer -$2bn - has already been stated.

Imbrinium should be aware that a nuclear variant is on offer for an additional fee. Although it may be possible to convert the vessel to run on biofuel, Randolph Defence Engineering Marine has no interest in such a project at this time.

[OOC: Sorry guys, I sort of forgot about this. Assume construction began from when you posted your order, so most should be done by now.]

$80,000,000,000 for 40 Type 81 Cavalier destroyers it is then

In that case we will accept our vessels "as is" with the existing gun mounts.

Pending a full in-service evaluation additional orders may be forthcoming.

Re: Destroyer designs.

Your Excellency,

The Empire of New Chalcedon is interested in a fleet of 128 (16 squadrons of 8) Type-81 Cavalier-class destroyers, and we are prepared to pay the asking price per unit. This is dependant upon the VLMS80 vertical missile launch systems being compatible with the Mk41 VLS missiles, as such missiles (or variants thereof) are standard armament for the Imperial Navy's units.

In addition, the Empire is interested in converting the power supply to nuclear or, failing that, natural gas power. The Empire has few oil reserves, and wishes to minimise its strategic dependance on oil imports.

We are prepared to pay for either of the following options:

a) $100 million (USD) bonus payment per unit equipped with such a viable power plant;
or
b) $5 billion (USD) for a viable design of such a power plant for the Cavalier-class destroyer, ready-to-build in the Imperial shipyards.

Failing either of these options, we are still prepared to purchase the units and convert the power plants in our own yards, provided that the VL compatibility condition is met.

Yours,

Astarte Petronia,
Imperial Secretary of the Marine.

REPLY TO ORDER AKNOLEDGMENT
Thank you for your quick and timely reply. We will await for delivery of our naval vessels.

The Commonwealth of Tolvan wishes to acquire an additional forty-five (45) Type 81 destroyers. The sum of $90 billion will be wired upon confirmation.

The following vessel order contracts have been signed:

The Ryou Black Islands - 40 hulls

Tolvan - 45 additional hulls

New Chalcedon - 128 hulls:

VLMS80 is larger or equal to Mk41 in every dimension, so with minor modifications can carry any missile Mk41 can. If, however, all your missiles are tailored to Mk41 operation, it may be more efficient to use the Mk41 VLS (greater number of cells, less expense in converting missiles), which the Company would be willing to do in our yards during construction for a nominal additional fee.

The vessel can be equipped with nuclear power plants. Converting gas turbine vessels, however, is very difficult and expensive. The Company is willing to build your Cavalier-class destroyers with nuclear reactors to equal shaft horsepower rating for the proposed premium.

Greal - 50 hulls

Cotland - 30 hulls

Clandonia Prime - 2,800 hulls. The Company intends to construct considerable additional capacity across the Georgian League in order to meet such a substantial order.

The United States of Hisperians would like to buy 60 ships priced at 120 billion USD. Transaction will be sent on aknowledgement of order.

After a lengthy review, the lack of stealth capability is the primary reasons admirals in the Glorious Republican Navy have rejected this design to replace the Illium class and the Delta class as its new Future Primary Surface Combatant (FPSC). We apologize.

Re: Destroyer designs.

Dear Sir/Madam,

The agreed-upon sum ($268.8bn, including the premium payments) has been wired to the account that you designated. Regarding the Mk41 VLS/VLMS80 compatibility, so long as the modifications are minor, the Empire will perform them in our own shipyards, in order to free up Praetonian slipways.

Regarding this, perhaps Randolph Engineering would be interested in utilising the advanced facilities in New Chalcedon? Ordinarily, we build our own ships (up to light carrier in size), so capacity is not a problem. The Crown is prepared to offer generous terms, including limited subsidies for any retooling needed. Please indicate acceptance/refusal soonest.

Yours,

Astarte Petronia
Imperial Secretary of the Marine.

Imperial Secretary of Industry.

Official Statement of the Free Republic of Kahanistan
Ministry of Defence

The Cavalier has proven itself in early testing. We would like to obtain 300 more to increase the size of our fleet for $600 billion USD.

We would also like to inquire about the compatibility of Questarian missiles with the Cavalier, as the only Praetonian missile we have production rights for is the Lance.

Signed,
Fleet Admiral Carl Jenkins,
Commander of Naval Operations,

Re: Type 81 Cavalier-class Destroyer Purchase

After careful review of the proposal brought forth by Rear Admiral Adam Trenton to rearm and redevelop the Commonwealth's Fleet, the Board has granted the approval for the purchase for 40 Type 81 Cavalier-class Destroyers to be constructed for the Royal Navy by the shipyards of Praetonia. One request is that these vessels be outfitted with nuclear reactors, as per section G82 of the Green Bill of the United Commonwealth to reduce carbon-using vessels in the Royal Navy.
