對啊我都念外文的耶，要不要看研發當時，英國人自己對type45防空系統的評價，這個階段也是老共決定不要用的主要階段，事後諸葛都是無聊的，何況你舉的例子根本有問題，知道在哪嘛？不知道...再去goo一下吧，提示一下喔，Aster30跟標準三根本不是同一個檔次的產品喔？　還看不懂？　那就沒辦法了。

言歸正傳，看看英國佬那時吞下Aster系統之後的苦水...

UK’s Type 45 destroyer: late, expensive and naked :Parliamentary report slams Royal Navy’s latest air-defence destroyer programme


09:13 GMT, June 24, 2009 The Public Accounts Committee (PAC) of the UK House of Commons yesterday issued a report on the UK's Type 45 destroyer programme, which is expected to become the backbone of the Royal Navy's air defence capabilities, but faces a number of serious problems resulting in increased costs and serious delays.

Following an audit by the National Audit Office (NAO), the PAC examined the capabilities provided by the Type 45 destroyer, the reasons for the rising costs and delays, and identified lessons learned for the aircraft carrier project.

The committee acknowledged that the Type 45 would provide the Royal Navy with a world-class military capability. However, the report also notes that serious mistakes have been made in the early stages of the procurement of the Type 45 destroyer, including unrealistic calculations and time objectives. “The project management arrangements on the Type 45 were poor and allowed the culture of over-optimism to persist for too long,” it was noted in the report. Following a far-reaching review of the project, the contract was renegotiated in 2007 and, since then, there have been no further cost increases or delays.


Equipment not introduced in time while budget rises

Although the First of Class will enter service in 2009 – two years later than planed – it will not have the Principal Anti-Air Missile System (PAAMS), also known as known as “Sea Viper”, which will not achieve full operational capability until 2011. Other equipment and capabilities to enhance the ship's ability to conduct anti-air warfare operations will also not be fitted until after the ship enters service. This means that the Type 45 will not have any anti-air capability (which it had originally been built for) until, at least, 2011.

As a result of the delays, the Department had to extend the life of the Type 42 destroyers longer than planned. “These ships are increasingly expensive to maintain, provide a more limited capability than the Type 45 and are more vulnerable to the most up-to-date threats from a modern enemy,” the committee notes.

Beyond that, the report sees the original budget exceeded by some £1.5 billion ($2.45 billion). The report says that the ministry “is confident that it will avoid making the same mistakes in the project management arrangements” on its two new aircraft carriers. “Agreeing [to] a fixed price too early, and not pricing all the requirements at the time of the contract, meant the Type 45 was at risk of cost growth. The [ministry] believes it will not fall into the same trap on the carriers,” the committee notes.

The Minister for Defence Equipment and Support, Quentin Davies, responded to the report by saying: “The Type 45 will be the largest, most powerful air defence destroyer ever built for the Royal Navy. It will set new standards in air defence, capable of defending its company from multiple attacks by the most sophisticated anti-ship missiles and aircraft.”

He also added, “by the time she enters service, the Type 45 will already have proven a level of anti-air warfare performance significantly higher than any other ship. Against this background, the government is surprised and disappointed that the Committee does not recognise the extensive trials that have taken place. In these circumstances, the use of the word ‘disgrace’ obviously makes no sense at all and is absurd.”


Half the number for the same job

The Royal Navy originally intended to procure 12 Type 45 air defence destroyers, designed to replace its Type 42s. However, revised requirements and budgetary pressures saw this number cut, at first, to eight. The report now stated that because of reduced threats, revised planning assumptions and an intended improved network capability, this number may further shrink to just six vessels. However, the reduction in the number of destroyers from eight to six means it will be more challenging for the Department to meet its policy requirement of five destroyers available for tasking at any time, the report states.

Of the six Type 45 Destroyers, four ships are in the water (Daring, Dauntless, Diamond, Dragon) while the other two vessels (Defender, Duncan) will be launched in late 2009 and 2010, respectively. The First of Class (HMS Daring) is currently completing final MOD managed trials and acceptance prior to entering service with the Royal Navy in 2010. The remaining ships will enter service progressively through the middle of the next decade.

The prime role of the Type 45 Destroyer will be air defence: protecting UK national and allied/coalition forces against enemy aircraft and missiles. It will carry the world-leading Sea Viper Missile System designed by EUROPAAMS, a joint venture between Eurosam (66%) and MBDA subsidiary UKAMS (33%) as well as the Sampson multi-function radar, built by BAE Systems INSYTE. The Type 45 warship’s prime contractor is BVT Surface Fleet Ltd.
