Amongst informed defence commentators it has been an open secret for several years, but on 2. January a BBC report finally put the engine problems of the Type 4. The Mo. D has consistently played down the seriousness of the issue, that had on occasions resulted in total propulsion and electrical failure, leaving ships dead in the water. Even Parliamentary questions were met with vague assurances that progress was being made. The media coverage has since been predictably excessive, giving the unfortunate impression that Type 4.

Although it might not seem like. There is one reason and one reason only the Royal Navy and Ministry of Defence have changed from five Non TAS General Purpose Type 26 to five Type 31.

Integrated Electric Propulsion IEP. There are many advantages associated with IEP, fuel efficiency, flexibility in locating the engines and a supposedly reduced maintenance and manning requirement. In basic terms, two WR 2. GTs and two Wartsila 2. MW diesel generators provide AC power for the motors that propel the ship as well as the power for the ships systems weapons, sensors lighting etc. The WR 2. 1 GTs were designed in an international partnership with Rolls Royce and Northrop Grumman Marine Systems. The turbines are of a sound design but have an intercooler recuperator that recovers heat from the exhaust and recycles it into the engine, making it more fuel efficient and reducing the ships thermal signature. Unfortunately the intercooler unit has a major design flaw and causes the GTs to fail occasionally. When this happens, the electrical load on the diesel generators can become too great and they trip out, leaving the ship with no source of power or propulsion. The Mo. D has not revealed how frequently these blackouts have occurred but the first 2 ships, HMS Daring and HMS Dauntless seem to have suffered the most. The first indication of problems was as far back as 2. HMS Daring lost all power in mid Atlantic and had to be repaired in Canada. Although the Type 4. An indication that all is not well could be seen by the number of Type 4. Portsmouth at any given time during the last few years. Historically the RN has never been a fleet of harbour queens and todays over worked navy can ill afford unreliable ships. HMS Daring entered service in 2. It is obviously dangerous from a seamanship and navigational point of view to suddenly lose propulsion at any time. It is even more serious when operating in a high threat environment as the ship would be a sitting duck. The otherwise highly successful Type 4. Great credit must go to the RNs long suffering mechanical engineers who appear to have always been able to restore power fairly quickly. The Mo. D states that A Type 4. As in so many other cases, the RN has managed to work around the problem to some extent and find fixes that reduce the number of electrical failures. Under normal circumstances the Type 4. Type 4. 2 predecessors. When the Type 2. 3 Frigates first entered service they lacked a computerised command system, a similarly serious flaw in a new warship. There was determination that the Type 4. The Type 4. 5 has become the gold standard in air defence and air traffic management, it has become the goalkeeper of choice for US aircraft carriers who recognise it has the edge, even over their renowned AEGIS system. Despite the issues, the Type 4. The propulsion problems will be fixed and the platform has the capacity for major future upgrades. A radical cure. A feasibility study into upgrading the generators was completed by BAES and the Mo. D in March 2. 01. The funding for the Type 4. November 2. 01. 5 SDSR and at least the problem has finally been recognised and funds are in place. Each vessel will have to be dry docked, large openings cut in the hull and one or possibly two new diesel generator sets slid into place. Type 4. 5 destroyer propulsion general arrangement. Removing and replacing the diesel generator sets would appear to present significant work. Image Rolls Royce. Replacement of the WR 2. GTs is not a practical option. Awesome Board Review Notes there. Instead additional or more powerful diesel generators will provide long term redundancy and assurance that electrical supplies can be maintained in the event of GT failure. The good news is that the large Type 4. The rectification work on the six ships will be done one by one as part of the normal major refit cycle. This will extend the length of the refits but should not have an especially dramatic effect on frontline availability. A pioneering legacy. It is ironic that the RN is suffering with propulsion problems, having had a great history of propulsion innovation and success. The steam turbine was a British invention and in HMS Dreadnought 1. The steam turbine drove the majority of major warships for the next 6. HMS Amazon 1. 97. GT warship and British engines were subsequently exported to many foreign navies. Much of the world renowned expertise in naval GT design was derived from an obscure and secretive facility, the Pyestock National Gas Turbine Establishment at Farnborough which tested developed marine and aero engines until it was closed in 2. One of Pyestocks last projects was some of the initial development of the WR 2. Rolls Royce and Northrop Grumman. Reliance on computer modelling signalled the end for Pyestock but with hindsight perhaps there is no substitute for real world testing. It is interesting to note that recently Rolls Royce opened a brand new testing facility for the WR 2. MT 3. 0 GTs Which will power the QE aircraft carriers and Type 2. Culpability and compensationBAE Systems, the prime contractor, ran a competition to select the pair of gas turbines that will power each warship. Excellent bids were received from Rolls Royce plc, offering the WR 2. General Electric Company, offering the LM2. The prime contractor advised us that both engines met the programme requirements, and that either would be acceptable to the Royal Navy. Therefore, it has been a difficult task to decide between the two bids. On balance, we have decided to select the Royce WR 2. The LM2. 50. 0 is a mature product it is in volume production and available at an attractive price. We accept that the WR 2. Those factors, many of which fall outside the type 4. Rolls Royce engines in the Royal Navy, and particular aspects of Royal Navy fleetwide operations for which the Rolls Royce engine is well suited. Geoff Hoon, Secretary of State for Defence, House of Commons, 1st November 2. Essentially the Labour administration of the time took a calculated risk that untested British GTs would be a better bet than a tried and trusted American option. The British jobs benefits, together with apparent efficiency gains offered by the WR2. Although Geoff Hoon is considered to have been something of a blundering Defence Minister, in this instance it was not an unreasonable decision, especially given the good track record of UK GT innovation. BAES could quite reasonably claim in court that they simply advised the client who took the more risky option. However BAES has not made any gesture of goodwill and have not funded any rectification work on the Type 4. Destroyers. Meanwhile they benefit from on going an in service support contract for the Type 4. Whether Rolls Royce or Northrop Grumman will accept any legal liability seems unlikely and it will be the poor taxpayer will be footing the bill. This unplanned expenditure is also likely to further delay any plans for fitting MK4.
