PRIORITISING CAPABILITY NEEDS AND FUNDING
13. The purpose of the Type 45 Destroyer is to provide
air defence to the fleet, for which it will deploy the Principal
Anti-Air Missile System (PAAMS).
The Comptroller and Auditor General's report stated that the first
three Type 45 Destroyers would enter service with some capability
shortfalls because they had been traded-off to make the ships
affordable and to enable them to be brought into service sooner.
In consequence, they would not have a sonar. In evidence, Vice
Admiral Blackham said that he believed that a ship should not
go to sea without a sonar.
Since the Department first started working on the Type 45 Destroyer,
he had always been quite clear that a vessel which did not have
a sonar was a non-deployable vessel in any but the most benign
Figure 2 sets out the chronology of the decision to fit a sonar
on the first three Type 45 Destroyers.

Position on fitting the sonar
22 November 2000:
The Comptroller and Auditor General's report on the Major Projects Report 2000 reported that for the first three Type 45 Destroyers the sonar capability had been omitted.
The report states that the lack of sonar could impose operational and ship scheduling constraints on the initial ships until it was fitted. For example, without sonar it was unlikely that the Type 45 Destroyers would be deployed alone to theatres where a significant submarine threat was perceived.
20 December 2000:
The Department places an order for the first three ships, 'fit to receive' a sonar.
The order is in line with the specification which did not call for a sonar but called for the ships to be 'fit to receive' a sonar.
Early 2001 (unspecified date before 15 January)
The Department decides fitting a sonar to the first three ships is affordable within the budget.
The overall budget for the Type 45 Destroyer included provision for the fitting of a sonar under an Incremental Acquisition Plan. Until the Demonstration and First of Class Manufacture contract was placed the Chief of Defence Procurement did not know whether funding headroom would be available early enough to allow the sonar to be fitted on build to the First of Class vessel.
15 January 2001
Vice Admiral Blackham confirms that it was the plan that the first Type 45 Destroyers would enter service with an Anti-Submarine Warfare sonar fitted.
Vice Admiral Blackham states that he had never been prepared to send any ship to sea without a sonar,and agrees that the sonar is a vital part of a ship, without which a ship should not be accepted at all.
The Chief of Defence Procurement admitted that the words in the Comptroller and Auditor General's report concerning the fitting of a sonar to the Type 45 Destroyer had hit home inside the Department and had caused the Department to have a rethink. He said that the horrific reality of the report helped all of them in the Department to reconsider their view. The Department did not need to take a final view on fitting a sonar at the stage he placed the order but he needed to get the prime contract rolling because that started design of the ship and otherwise the ships would be late.
The Chief of Defence Procurement confirmed that the sonar would cost about one and a half per cent of the ship price and assured us that it had been affordable within the budget and there had been no cuts elsewhere in order to make the sonar affordable.
14. Vice Admiral Blackham was asked what sort of
sonar the Type 45 Destroyers would have when they entered service.
He said that the Department had been giving thought to the possibilities
and had a range of choices including various off-the-shelf sonars
and sonars in the Royal Navy's own ships which were becoming redundant
as the ships were paid off. Our predecessors asked whether it
was going to be effective in every theatre against every perceived
and were assured that whichever sonar the Department chose would
be effective and value for money. As the Customer, he was not
interested in having a sonar which was unable to cope with the
sorts of submarine threats that the Royal Navy might face. Off-the
shelf sonars were widely fitted in the ships of a large number
of nations and sonars from ships that were being paid off were
not necessarily redundant and were widely fitted in ships which
would continue in service.
15. Following the United Kingdom's withdrawal from
Medium Range TRIGAT, the Army is conducting an Anti-Armour Balance
of Investment study to establish the capability its mechanised
and armoured battlegroups required from short, medium and long-range
anti-armour systems. The Department considered the possibility
of conducting the study before approval was given to join the
industrialisation and production phase of Medium Range TRIGAT
in June 1999 but, at the time, decided that this was unnecessary.
Since there had been doubts about the suitability of Medium Range
TRIGAT for some time, the Department was asked why it had not
conducted the Balance of Investment study earlier, which might
have pointed to an earlier and cheaper withdrawal. The Department
said that in 1999 it had only 12 months previously completed the
strategic defence review which confirmed the place of Medium Range
TRIGAT, but agreed that it should have conducted the study earlier.
16. Asked what advantage there was to the Armed Services
in delaying Brimstone in order to align its deployment with the
Tornado GR4 Package 2 update, the Chief of Defence Procurement
said that the Department started the Brimstone programme on the
basis that the Harrier GR7 would be the lead aircraft in terms
of introducing its capability. Brimstone required a digital databus
and the Department had had some difficulty in sorting out how
to fit the equivalent of a digital databus in the Harrier GR7.
Delays to the Harrier modification programme became such that
it was clear that the Tornado was going to be the first aircraft
capable of introducing Brimstone into Royal Air Force service.
The Chief of Defence Procurement said that the advantage to the
frontline forces lay in reducing the delay for Brimstone's introduction
into service by choosing the Tornado rather than the Harrier.
17. The Chief of Defence Procurement agreed that
Brimstone could potentially be deployed and used on the Tornado
without the Package 2 update, but the weapon's effectiveness would
be much reduced and the pilot's workload much increased.
The decision that it was not a sensible proposition to put Brimstone
on Tornado before the Package 2 update was taken by the Customer
organisation in consultation with the user.
18. Delays to Brimstone will cost the Department
around £48 million in total.
The additional costs reflect the fact that, while the Department
was procuring a new weapon (Brimstone) which should have come
into service earlier, it was upgrading equipment (BL755) and buying
a weapon off the shelf (Maverick) to plug a capability gap. Asked
why the upgrade to BL755 for Kosovo was twice as costly as it
would otherwise have been, the Chief of Defence Procurement replied
that there was a proportionately higher cost to upgrading a smaller
proportion of BL755s,
and the original contractor who produced the fuse sensors had
stopped manufacturing them.
19. In summer 2000, the Department decided to reduce
the number of Brimstone missiles it required by 25 per cent.
The Chief of Defence Procurement confirmed that the contract was
effectively a fixed price contract for a fixed number of missiles.
Pressed on whether this meant that the Department would not get
any saving, he said that the Department was in discussion with
industry over the level of savings that might be realised from
the reduction in missile numbers. It was a package deal contract
rolling up both development and production and he told the Committee
that there would be no saving in the research and development
component of the contract which was something approaching 50 per
cent of the total contract price. This meant that on a pro rata
basis the Department would at best save about half the price.
The Department hoped to conclude its discussions with industry
20. In September 2000, the Department placed an order
for Maverick G missiles.
Asked why it did not decide to buy Maverick earlier to fill the
capability gap caused by the delay of Brimstone instead of upgrading
the Chief of Defence Procurement said that at the time the Department
decided to upgrade BL755 Brimstone's in-service date would have
been closer, but the Brimstone in-service date (currently October
2002) had slipped.
21. Asked whether it had wasted money upgrading BL755
because it had less than 5 per cent of the capability of Brimstone
against modern tanks,
the Department said that it was extremely useful against soft
skinned targets, such as patrol cars and missile launching vehicles.
The Chief of Defence Procurement said that the Department was
now beginning to think that BL755 would not be phased out when
Brimstone came into service because its usefulness against such
targets meant there was a long term prospect for it.
22. Asked how much less effective Sidewinder was
compared to the Advanced Short Range Air-to-Air Missile (ASRAAM).
Vice Admiral Blackham responded that ASRAAM was a short-range
missile designed to be very agile against other high performance
fighters. Sidewinder was predominantly an infrared-seeking weapon
but it was not out of date
and the Department did not plan to dispense with the AIM 9 Sidewinder.
Rather, the United Kingdom planned to go on using it in a range
of roles for which it was suitable for another 20 years, as did
the United States.
Thus the Department would have a combination of Sidewinder missiles
and ASRAAM missiles.
23. The Department was asked to explain why a generic
air-to-air missile was no longer deemed to be a necessary part
of the Apache Attack Helicopter requirement. In reply, Vice Admiral
Blackham said that the Apache was part of an integrated Air Defence
Programme aimed at defending the airspace within which United
Kingdom Forces were going to operate, and it would fly within
an overall air defence umbrella. As a result of studies the Department
had done it had concluded that the air-to-air missile was not
needed and that the money that might have been spent on the missile
was better invested in other parts of the United Kingdom's overall
air defence capability.
24. The cost of the Eurofighter programme has been
reduced by £32 million after the military Customer decided
that the gun was no longer required.
The reasons for deleting the requirement for a gun on Eurofighter
are set out in Figure 3. Summarising the arguments, Vice Admiral
Blackham said that the Department had concluded, in consultation
with the Royal Air Force that, in the future operational roles
for which Eurofighter was required, the minimal value of a gun
was more than outweighed by its considerable disadvantages and
He said that the Department never judged something against not
having it, but against what other things it could do with the
In this case, the Department could spend its money better elsewhere.
|Figure 3: Reasons for the deletion of the requirement for a gun on Eurofighter
Eurofighter's long range capability should be emphasised
To perform its role effectively, Eurofighter's armaments should emphasise not the very short-range capability that gun would offer, but the long-range capability to be offered initially by the Advanced Medium-Range Air-to-Air Missile (AMRAAM) and later by the Meteor beyond visual range air-to-air missile.
In short-range engagements, the minimum range capability and agility of the missiles that Eurofighter would carry, together with its planned helmet-mounted sight targeting system, offered the pilot a shot with a high probability of success in almost every conceivable situation. ASRAAM had already proved itself against typical countermeasure and was designed to overcome extreme levels of countermeasures.
There is not a satisfactory use for a cannon.
The Department looked very hard at what the benefits of the gun were, using real scenarios, and had not found very many. A gun could be seen as a defence of last resort when all the aircraft's missiles had been fired or should advanced hostile aircraft have decoyed Eurofighter's air-to-air missiles successfully. However, even in these scenarios the gun's usefulness would be severely limited because of the possibility of engagement by missile armed aircraft from well outside the gun's range. If a United Kingdom pilot closed on a hostile target to within the range of a gun, he would be placing the aircraft and himself at unnecessarily high risk of being shot down by the hostile aircraft's missiles.
Guns have not been used very much in recent operations
To the best of the Equipment Capability Customer's knowledge a gun had been used by a fighter aircraft on only two occasions in the last 10 to 15 years, during the Gulf War when an A10 used a gun against a helicopter.
Guns cause additional stress and wear for the aircraft and require additional training
Using its normal techniques for analysing scenarios, the Department had found a number of disadvantages caused by the gun including recoil shock effects on the aircraft's electronics, corrosive effects from the gun's exhaust gases, additional fatigue in the airframe and added substantial training requirements.
25. Given what the Department had said about the
cannon on the Eurofighter, our predecessors asked for a list of
other air forces which were buying fighters without a cannon.
The Department responded that our partner nations intended to
retain the gun on Eurofighter. The American F-14, F-15, F/A-18
all had internal guns and the F-22 was planned to have one, though
the F-117 did not have a gun. The Russian MiG-29 and the Su-27/31
also had guns as did Gripen and Rafale. The Department noted that
some of these aircraft entered many years ago when missile technology
was far less advanced and it was not currently planned to fit
an internal gun to the Short Take-Off and Vertical Landing variant
of Joint Strike Fighter. This variant of the Joint Strike Fighter
would be able to carry an externally mounted gun which could be
put on and removed from the aircraft for particular missions.
26. The Type 45 Destroyer's main gun armament will
meet some, but not all, of the Navy's requirements and was not
seen as a long-term solution.
Asked why this was so, Vice Admiral Blackham said that the main
purpose of a gun on a ship of this sort was to provide naval gunfire
support to troops ashore. This was an Army requirement, not a
and it lay within the battlefield engagement part of his organisation
to decide how this was best met. One of the things his Equipment
Capability Customer organisation had been established to do was
to take a view across the whole of defence activity and to conduct
balance of investment exercises. These were being conducted to
look at the range of weapons, shipborne, airborne and landborne
which could contribute to fire support for the troops. Vice Admiral
Blackham said that the reason they had not been started earlier
was because his organisation was only set up in October 1999.
27. Whilst the Navy would like to be able to provide
gunfire support with long-range guns and heavier, more precise
ammunition, Vice Admiral Blackham was not yet convinced that that
was the best answer. It would only be when the full balance of
investment into the ways in which support was applied to troops
had been completed that he would be sure about the best mix of
weapons to meet the task.
The intention was that there would be a gun on the Type 45 Destroyer,
but whether it would be the same gun which would be installed
in all the ships for their entire life, until about 2040, he could
not say. It would be extraordinary if the Type 45 Destroyer had
not had a large number of changes to its weapons systems in that
28. There was confusion between the Capability Customer
and the Defence Procurement Agency over the fitting of a sonar
to the first three Type 45 destroyers. The Department only recognised
the lack of sonar as a fundamental issue when it was highlighted
by the C&AG's report. The Committee finds it difficult to
understand how the planning for these ships could exclude such
vital pieces of kit and views with concern that such a possibility
could have been seriously considered. The Committee therefore
recommends that the Department should review the arrangements
for communication between the Equipment Capability Customer and
the Defence Procurement Agency to ensure that those arrangements
can be relied on to convey exactly what is required.
29. The Chief of Defence Procurement said that the
sonar was being procured because of the headroom provided by the
lower than expected contract price secured on the prime contract.
The statement implies that, if the contract price had been a few
per cent higher, there might have been no sonar. Vice Admiral
Blackham suggested that, if necessary, he would have looked to
make the sonar affordable from elsewhere in his budget. That is
not satisfactory and the Customer Capability organisation needs
to develop a rigorous approach to planning capability which will
ensure that key requirements such as the Type 45 sonar are given
the budget priority which Vice Admiral Blackham suggests they
30. Several different sources are being considered
for the Type 45 Destroyer sonar, including off-the-shelf procurement
of an existing sonar or the re-use of sonars from ships which
have been withdrawn from service. Vice Admiral Blackham assured
our predecessors that, whatever sonar was fitted to the Type 45,
it would be cost-effective and capable of deployment in all theatres.
The decision to fit the sonar must not delay the entry into service
of the badly needed improvement in the anti-air warfare capability
of the Royal Navy which the Type 45 Destroyer will provide.
31. The Department has not always undertaken the
right analyses at the right time. It accepts, for example, that
it should have undertaken a study on anti-armour weapons before
committing to industrialisation and production of Medium Range
TRIGAT, rather than after the subsequent decision to withdraw.
For the future, the Equipment Capability Customer organisation
needs to specify the appropriate stage for such analyses at the
outset, and ensure their more timely completion.
32. The Department's strategy for meeting its anti-armour
weapon requirements appears to have evolved incoherently over
time and with cost penalties. The Department paid a premium of
around double the unit cost of an earlier order to upgrade additional
BL755 cluster bombs for the Kosovo campaign, reduced the number
of Brimstone missiles being procured with no prospect of a proportional
saving in price, and purchased Maverick missiles at extra cost.
The Equipment Capability Customer should make timely judgements
on the number and mix of weapons required to enable cost effective
procurement and avoid such cost penalties.
33. In the airborne anti-armour role, the Department
suggested that three weapons would have a part to play in future,
the existing RBL755, and the new procurements of Brimstone and
Maverick. Similarly, the new ASRAAM missile and existing Sidewinder
missile will be used side-by-side for the next 20 years. In reaching
such judgements, the Department should quantify the cost and operational
merits and drawbacks of operating such mixed inventories.
34. The United Kingdom's Apache helicopters will
not be fitted with an air-to-air missile because the Equipment
Capability Customer decided that procuring an air-to-air missile
would not be the best use of resources given the other air defence
assets available. Similarly, the Customer considered when suitable
aircraft platforms would become available in deciding to reschedule
the Brimstone missile. The Customer should take a similarly holistic
view in identifying how best to meet other capability needs, and
should adapt its arrangements for evaluating future needs so as
to embed this good practice.
35. Eurofighter will enter service with the Royal
Air Force without a gun because the Department has decided to
delete the requirement, saving £32 million. The Department
put forward persuasive operational arguments to justify the decision
not to fit a gun. To remove any doubt about the decision to delete
the gun, it would be wise for the Department to cross-check why
our Eurofighter partner nations are still fitting the gun and
why other countries fit guns to their aircraft.
36. The Equipment Capability Customer is conducting
a Balance of Investment study looking at what mix of air-, landand
sea-based weapons could best meet the Army's long range fire requirement.
The Customer will make a final decision on the type of gun to
be fitted to the Type 45 Destroyer once this study is completed.
The Customer should ensure that the timing of this decision does
not adversely affect the timescale for the design and production
of the Type 45 Destroyer.
