    Probably a silly question on my part, but:

    What does the PLAAF call its Su-27SK and Su-27UBK (the ones imported from Russia)? Su-27 or J-11?

    The E-2D is a rotating AESA dish.

    And saved weight – important on the E-2D.

    Has there been any mention of India-specific changes?

    For example I doubt they will go with Link 16, so maybe ODL datalink?

    Wedgetail has 360° capability. As can be seen in the top photo the side arrays are on pylon (large gray antenna), the top hat fore and aft arrays are on the top (black antenna).

    One advantage of the Israeli Gulfstream conformal design was ease of installation. The side conformal arrays used the former windows as cable ducts. This resulted in less effort in clearing the aircraft for flight as the airframe was not compromised.

    As per: http://www.publications.parliament.uk/pa/cm201011/cmhansrd/cm101124/text/101124w0002.htm#10112471000042

    The 70000 Typhoon figure:

    “The MOD calculates the full cost of aircraft per flying hour. The current rates for our fast jets are shown in the table. These figures include forward and depth servicing, fuel costs, crew costs, training costs, cost of capital charge, depreciation and amortisation. The Typhoon cost per flying hour reflects the build up of the fleet with small numbers of aircraft currently in-service. This cost will comparatively reduce as the fleet builds and is expected to be similar to our other fast jet fleets when we reach a steady state position.”

    Also of interest:
    Tornado GR4 – 35,000
    Harrier GR7/GR9 – 37,000
    Tornado F3 – 43,000

    Without knowing what they mean (just test gear, fly away tool boxes, how many spare engines, etc):

    Typhoon deployment of a squadron (probably NATO standard, white and two – I mean 12 aircraft) is 3/4ths of one (not a typo) C-130 load for four weeks.

    Rafale is four C-130 loads to deploy 20 aircraft squadron for 30 days. French Air Force was talking 60 ground crew per 20 a/c squadron (ISTR RAF Tornado squadron is 120-150?).

    Whichever India selects they are in for a leap forward in capability……

    Thats important for the German Air Force as GAF does flightline maintenance with everything else by industry.

    Any ideas on the Indian maintenance model?

    Eurofighter maintenance:
    Maintenance costs <25% of life cycle costs (not very helpful – whats the life cycle cost).
    Eurofighter is contractually obliged to achieve none maintenance man hours per flight hour (half Tornado, one hour more than Hawk T1)
    50 defects repairable in one hour, 95% in three hours. Engine change in 45 minutes by four crew.

    Don’t forget Eurofighter has DVI (direct voice input) which is gotta improve the MMI….. 😉 The plan is to use DVI for routine tasks (change radio frequencies, displays) and HOTAS for time-critical stuff. It uses the Attack and ID System (AIS) for onboard and offboard track fusion. One the advantages of having multiple displays is teh radar can show vertical and horizontal (range and altitude) in large format and an easy to digest manner.

    The ECM system can detect missile midcourse datalinks – for example if that Mica IR shot is using its midcourse datalink…. Mirage 2000-5 Mk2 also has this ability.

    Didn’t realise but Eurofighters EJ200 engines have been updated a number of times – the 2004 EJ202-101 FOC has a modified HP compressor and LP turbine – a cockpit switch increases dry thrust by 15% and reheat by 5.5%. Engines are designed for a 6000 hour life.

    And of course with HMD and IRIS-T or ASRAAM you don’t even have to point the nose near a target to fire WVR.

    They aren’t my numbers. They are from an article in World Air Power Journal Volume 35. I’d tell you the author, but I’m sure you can already guess….

    Whats the formulae for converting between RCS and ranges again? I had it written somewhere, but cannot find it.

    Something like (3m2/5m2)^2 x range?

    Rafale random stuff:

    Agility greater than Mirage 2000 and F-16 (duh!) – ideal tactics were high altitude, loft MICA msls (hence the high range from the small MICA msls…), then low altitude into Doppler notch. Large wing, canards for higher pitch, high engine thrust.

    And ‘considerably more agile below 300 kts’.

    Its rated at 9G, 29° AOA and roll rate 270° second with AAM only.
    Fully loaded 5.5G, 20° AOA and 150° second roll rate.

    Acceleration given as 30 knots/second from 200-500 knots (10 seconds!).

    RBE2 radar ranges given as 130-140 km vs 3m2 and 100 km track. And 100 km vs lookdown target. Can track 32 targets whilst engaging 8 with Mica (4 in terminal phase, 4 midcourse guidance). Arcs given as +/- 60° azimuth (120° total).

    RBE2 AA AESA supposedly improves standard figures by 40% in range and and +/- 70° azimuth (140° total).

    One of the issues with early Rafale service was ‘poor radar range’. ISTR this has been fixed – no idea on what this does to ranges above.

    Nothing to see Eurofighter was optomised as a fighter, Rafale ‘omnirole’ – having said that, due to training and flight hours, French pilots are all trained in air to air, CAS, ASSM and SCALP EG use. Some are trained with Damocles and/or Reco NG.

    A recent article on the F-15C mentioned how they fight different fighters.

    F-16C – fight using lower speeds
    F-18C – fight in the high speed regime
    F-18E/F – stay out its high nose pointing arcs.

    As for CAPTOR, radar antenna is 70 cm diameter.

    Air Forces Monthly July 2000 – detected large cargo aircraft (commercial Airbus’s etc) at 200 nm (370 km) and 100 nm (185 km) for ‘fighters’.

    I think the track range is 160 km vs 5m2. Can track at last 20 and probably 30+ (Blue Vixen is 28).

    Edefense gave 160 km for 5m2 and 300 km – this seem like track ranges (see above).

    Sain says radar was 50% improved over APG-65 (doesn’t specify what they mean).

    Uses interleaved RWS, TWS and VS. Can TWS in entire 120 degree arc due to high scanning speed. Has automatic IFF and NCTR.

    P1E/SRP 12 (a funded upgrade for Tranche 2 currently underway) will add terrain avoidance, sea search, and GMIT radar modes. Supposed to enter service in late 2012.

    Eurofighter has acceleration from 200 kts to Mach 0.9+ in <20 seconds – also as 200 kts to Mach 1.0 at Low altitude in 30 seconds. QRA climb to 12192 m in 2 minutes.

    Supercruise is Mach 1.3 (World Air Power Journal 38, page 67). With 50% fuel and 6 AAM supercruise less than Mach 1.4.

    Air Forces Monthly May 2004 has turn ability Mach 1.6 @ 4-5 G. Turn radius is 3 km – given as Mach 1.5 @ 6.6 G.

    Subsonic agility greater than Su-27 and MiG-29 (it’d frigging wanna be!). Only F-22 and Su-35 with thrust vectoring are better (nose pointing).

    Supersonic agility close to F-22 instantaneous, although F-22 is better in sustained.

    Edefense also had “Detailed figures are classified, but an unofficial source says that the Typhoon has about a 1-square-meter RCS. Such a figure is quite a good achievement, since it is only about 0.13% of the RCS of the Su-27/30/35 and about 0.2% of the RCS of the MiG-29. However, it is significantly than the F/A-22’s figure, which is reportedly in the region of 0.05 sq m.”

    WAPJ 35 had 1/7th Su-27, 1/5th F/A-18, 1/3rd Rafale (yea I know, okay!).

    Gives generic Flanker at 7.7 m2, 5 m2 for MiG-29 and F/A-18, and 3m2 for Rafale (okay leave me alone! ). I’ve seen MiG-21 with 3m2.

    Germany gave the following figures at the recent India Air Show:
    <280 defects per 1000 hours (expected 100-200 with more experience), 6000 hour life
    F-4E was 39 inspections for 6000 hour life
    MiG-29 – 3600 hours, 47 inspections
    Tornado – 19 inspections for 6000 hours
    Eurofighter – 14 inspections for 6000 hours
    German AF does onboard and limited offboard maintenance. Industry does offboard – aircraft airframe, engine, ejection seat, etc. No duplication, fast operational support

    On of the F-35A requirements was bird-strike resistance at low altitudes – Gotta get below those S-300/-400 radar horizons…..

    ISTR the plan is take it ‘slightly above Mach 1.6’, so M1.6 should be the operational maximum.

    Have any Eurofighter countries declared the helmet-mounted display (HMD) operational?
