The Eurofighter project has been subject to several operational evaluations. These have been carried out, independently from the Eurofighter consortium, primarily by Britain's DERA, the Defence Evaluation and Research Agency (now split into QinetiQ and DSTL). Unlike many previous theoretical operational capability studies, the Eurofighter analysis utilised a true simulation approach. This was achieved through a number of networked battle simulation computers, termed JOUST, each of which can be flown by human pilots.


BVR Combat Rating
F-22 Raptor rating : 91% [1.61kB] 91%
Typhoon rating : 82% [1.4kB] 82%
Rafale rating : 50% [1.32kB] 50%
F-15C rating : 43% [1.23kB] 43%
F-18+ rating : 25% [1.15kB] 25%
F-18C rating : 21% [1.2kB] 21%
F-16C rating : 21% [1.21kB] 21%


This system was used to comprehensively evaluate the BVR (Beyond Visual Range) performance of the Eurofighter and other aircraft against an upgraded Su-27 Flanker (comparable to an Su-35 Super Flanker and its equivalents). The studies investigated all aspect best performances from the major systems on each aircraft; avionics, structure (including RCS data), engine performance (including fuel usage), defences and man-machine interfaces. In these tests the French Rafale utilised the Matra-BAe MICA air to air missile (which is the primary AA weapon of the French airforce) while the other aircraft used the Raytheon-Hughes AMRAAM.

These simulations concluded that Eurofighter has a win rating of 82% (100% equals always win, 0% equals always lose, 50% equals parity) against the target aircraft. A more typical way to present this data is as a combat exchange ratio, for the Typhoon this equals 4.5:1. In other words statistically one Eurofighter would be lost for every 4.5 Su-35 fighters shot down. This compares extremely favourably to the other aircraft (see also the BVR Combat Rating table); F-16C Falcon (0.3:1), F-15C Eagle (0.8:1), F-18C Hornet (0.3:1), F-18+ (0.4:1, NB this is not the current F-18E/F which is apparently a downgraded version of the F-18+ used in the studies) and Dassault Rafale (1:1). Only the LM/Boeing F-22 Raptor bettered the Eurofighter's performance with a combat exchange ratio of 10.1:1.

In addition to these overall combat performance results a number of individual comparisons have been made available. Of enormous importance for BVR combat is acceleration at medium altitudes and here the Eurofighter's acceleration at Mach 0.9 and 22,000ft equals that of the F-22. At supersonic velocities (Mach 1.6 and 36,000ft) the sustained turn rate of the Eurofighter betters all but the F-22, while its instantaneous turn rate is superior to the F-22. At low altitudes, Eurofighter can accelerate from 200kts to Mach 1.0 in under 30 seconds. In a similar vain to its supersonic performance, the sustained and instantaneous subsonic turn rates of the Eurofighter are bettered only by the F-22. Only the Rafale comes close to the matching the Eurofighter's capabilities in these comparisons.

An important point to keep in mind when examining this data is that full details on the simulations have not been released. Without this information it is not possible to determine whether Eurofighter optimal profiles were examined at the expense of more varied combat missions. However these studies do give some indication as to the potential of the Typhoon.

UK and Italy weight Eurofighter options
Reuters | Sep 14, 2007


LONDON: Defence officials from Britain and Italy have asked the Eurofighter consortium for information on their options as they weigh budgets to buy fighter jets from both Europe and the United States.

A spokesman for the Eurofighter consortium said it was working on implementation of an existing plan for the sale of 236 planes to four countries. This proposal is due by the end of the year.

These make up the last tranche of 620 ordered under the four-nation programme involving Britain, Germany, Italy and Spain.

"We were asked to deliver information on certain options for the UK and Italy to support their business cases," the Eurofighter spokesman said, noting defence officials in the two countries have to weigh budgets as they also consider how many of the Lockheed Martin Corp-led Joint Strike Fighter they might buy.

The Times, citing unnamed defence sources, reported on Thursday that the UK was seeking information from Eurofighter with a view to reducing, delaying or entirely cancelling its final order for 88 aircraft.

"I reject this as pure speculation," the Eurofighter spokesman said.

Any nation that reduces its orders would owe compensation to the others under the Eurofighter contract, which uses the level of orders to set terms for the deal including how many jobs are created in each of the four countries.

Another option for the nations is to take delivery of their planes and sell some of them on to other countries.

Aqui pode haver barganha!

The Ministry of Defence declined to comment on the newspaper report, but stated that negotiations on the third tranche of Eurofighter would last through 2008.

In addition to 88 for the UK, the final tranche calls for 68 for Germany, 46 for Italy and 34 for Spain.

The Eurofighter is built by a consortium of Airbus parent EADS, BAE Systems and Alenia Aeronautica, a unit of Italy's Finmeccanica.

UK govt trying to cut, delay or cancel Eurofighter Typhoon order - report
13-SEP-2007 08:17

LONDON (Thomson Financial) - The UK government is trying to reduce, delay or entirely cancel a 5 bln stg order for 88 Eurofighter Typhoon jets from a consortium including European aerospace group EADS and BAE Systems PLC, according to a report.

The Ministry of Defence (MoD) is in talks with the consortium about how much it would cost to cut the so-called Tranche 3 contract for the aircraft, the Times quoted the chief executive of EADS Defence Systems, Stefan Zoller, as saying.

Britain has already bought 144 of the jets for the Royal Air Force (RAF), but the UK Treasury will not allow the MoD to buy both Tranche 3 of Eurofighter and the Joint Strike Fighter, which will fly from the two new aircraft carriers being built for the Royal Navy, the newspaper quoted unidentified defence sources as saying.

A statement from the Saudi Arabian Defense Ministry released today (Sept. 17) confirms that the final contractual element of the government-to-government deal is now in place. It was followed several hours later by a short statement from the UK Defense Ministry.

The follow-on to the Al-Yamamah program, called Project Salaam, will be built around the purchase of 72 Eurofighter Typhoon aircraft. The last piece of the paper was signed on August 28th, and is thought to have been inked by Des Browne, the British Defense Secretary, and King Abdullah of Saudi Arabia.

The Saudi statement said the cost of the 72 aircraft was 4.43 billion pounds ($8.86 billion).

25 anos...

Só para terem uma ideia, a RAF está a vagar uma Base aérea completa (Coningsby) para os Sauditas albergarem o seu OCU ai. Se comparado este negócio com o dos Super Bugs para a Australia, até fica MUITO barato.

P...Q...P...iu!!!!!

Quer dizer que por esse preço é só encher o tanque e pagar o salário do piloto pra ter um Eurofighter voando por 25 anos

Como o financiamento para a compra certamente se paga em vários anos, esse é o tipo de negócio que fica barato com o tempo.

Eu quero dois esquadrões desses pra FAB já

Completa com quatro esquadrões de Gripen e pode passar a régua
