Of the possible contenders which fighter should Canada aim at for replacing the CF-18 or should it simply keep with the F-18s until some time in the distant future.
The way I see it the possibilities are the
USA/UK
F-35 Joint Strike Fighter
The new ground attack aircraft of the US and the UK with interest from numerous additional countries the Joint Strike Fighter is capable of STOVL (Short Take Off Vertical Landing) as well conventional take off and landing for airforces. A replacement to the, Sea Harrier, AV-8B, F-16, F-18A/C/D, and the A-10, the JSF is a stealthy multirole fighter designed to complement the F-18E/F and the F--22. The JSF is capable of both stand off warfare as well as close in air support of ground troops, the latter is perhaps its most convincing allure to the Canadian Military.
The Airforce Variant has a thrust to weight ratio of aproximately 1.11:1 and can carry 13,000 lbs in payload as well as cost approximately 45 Million dollars per unit. The F-35 has an advanced Avionics Suite including AESA radar, the service ceiling is approximately 48,000 ft and a maximum speed of mach 1.8. The Primary Contractor is Lockheed Martin, with Northrup Grumman and BAE Systems as major subcontractors.
(Other models vary in cost/performance)
USA
F-22A Raptor
The F-22A Tactical is perhaps one of the worlds most expensive fighter aircraft. With a flyaway cost of 130 million per plane, it is not the most expensive plane, but it certainly edges out most of its competition. This price is, however, not without benefit. The F22 features some of the most advanced avionics, engines, and radar cross section reducing techniques. Additionally it is easier and less expensive to maintain then it's predecessors.
The F-22 has a Thrust to weight ratio somewhere above 1.27:1 and can maintain supercruise at mach 1.7 without afterburners and push mach 2.42 with them, the service ceiling is at 68,000 ft. It has vectored thrust and an extremely advanced AESA radar which demonstrates unprecedented capabilities in keeping with US's typical dominance in the field of avionics suites.
France
Rafale
The Rafale is a french design developed after they withdrew from the Eurofighter Project, focusing instead upon ground attack, rather then upon air supremacy. The Rafale is a manueverable plane with a high angle of attack, as well as the capability to be launched from an aircraft carrier. The materials and components have been designed to reduce radar signatures, and the plane benefits from a fully integrated fire control system.
The Flyaway cost varies between 104 million USD and 130 USD. The Plane is capable of Mach 2+ and a service ceiling of 60,000 ft.
Russia
Su-30MK Sukhoi
The Su-30 Flanker is a derivative of the Su-27 and is among the more recent developments from Russia. It is largely a multi-role fighter which many western nations benchmark themselves against, and reasonable proliferation, with variants sold to the Ukraine, China, and India. It is considered the Russian Equivalent of the f-15
Mig-29 Fulcrum
The Mig-29 is a High Performance Combat Aircraft with proliferation to over 25 countries, it can be considered the standard opposing force fighter in the coming decades. The Mig-29 has a definite edge on most all US Fighters, having won in mock skirmishes between Australian F-18s and Malaysian Mig-29s. The Mig-29 also has an arguable edge on both the f-15 and f-16.
Sweden
JAS-39 Gripen
The Gripen multirole fighter is lighter and smaller then its Eurofighter counterpart, and as a result has a faster rate of climb. The Gripen is designed with "todays defense budget in mind" and cheaper to procure, as well as easier to maintain, a feature which, according to its manufactures, should allow it to field twice as many sorties as its rivals. It has a comparable Avionics suite to its European Counterparts. The Cost is the lowest of the bunch, at $25 million, outperforming even the JSF.
The Gripen has a ceiling of 50,000 ft and can carry around 14,330 lbs.
Europe
EF-2000 Eurofighter (Typhoon)
Europe's newest Air Supremacy fighter follows with the current style of european aircraft, with a delta wing and canards. The fighter is comparable to the F-22 in the sense that both fighters are designed primarily for air to air engagements, but the eurofighter lacks the stealth traits of the f-22 although it does incorporate some stealth charachteristics. According to US Airforce General John P Lumper "the Eurofighter is both agile and sophisticated, but is still difficult to compare to the F/A-22 Raptor. They are different kinds of airplanes to start with; it's like asking us to compare a NASCAR car with a Formula 1 car. They are both exciting in different ways, but they are designed for different levels of performance."
The Eurofighter cruises at mach 1.2, can attain mach 2.0+ and can carry a payload of around 14,300 lbs. By 2010 there are plans to upgrade the Eurofighters with AESA radars to bring them up to US standards. The Service Ceiling exists at 60,000 ft and the fly away cost ends up at approximately 75 million USD per plane.
