    how old are the newest 300 F15Es ? if < 10 yrs old, they can
    comfortably perform for another 20 yrs atleast.

    more info. the SU30MK is just a 2-seater Su27 (the 10 meant
    for indonesia have a limited ground attack mode in diving profile.)
    AFM did report once that datalink was being used by IAF so its
    there.

    The RLPK-27

    The SU-27P is fitted with RLPK-27 radar sighting system (rahdiolokatseeonnaya preetsel’naya sistema). This comprises the Phazotron (NIIR) N-001 Mech (sword) coherent pulse-doppler fire control radar. The N-001 received the NATO-codename Slot Back. The radar has a look-sown/shoot-down capability. The radar has a scanner diameter of 1.07 m (3 ft 6 in) and a target detection range (for a mig-21 sized target) of 100 km (53.9 nm) in the forward hemisphere in the look-up mode, this drops to 90 km (48.5 nm) in the look-down mode and 40 km (18.88 nm) in the rear hemisphere in the look-up mode, this drops to 30 km (16.2 nm) in the look-down mode. The radar is capable of illuminating the target so the pilot can fire a semi-active radar homing (SARH) missile to it. Another nice feature of the N-001 is that it can track ECM-sources. The radar is very resistant to ECMs and has a dual- target engagement capability (although it’s believed that the Flankers in service with the Russian Air Force don’t have a dual-target engagement capability). The radar can also be used in conjunction with the OEPS-27.

    The OEPS-27

    Another feature onboard the Su-27P is the OEPS-27 optoelectronic sighting system (optikoelektronnaya preetsel’naya sistema). This comprises the IRST and the helmet-mounted sight. The Su-27 is the world’s first fighter that is equipped with such a capable optoelectronic sighting system. The OEPS-27 has lots of advantages: The pilot can track and engage targets without revealing himself, he can use the IRST in conjunction with the radar for target information updates and he can use it as a back-up when the radar fails. The IRST fitted in the OEPS-27 is the Model 36sh which has a detection range for an outbound target of 50 km (27 nm) and 15 km (8.1 nm) for an inbound target. The OEPS-27 has a look-down/shoot-down capability and is capable of tracking during day and night and even in bad weather. The HMS fitted in the OEPS-27 enables the pilot to lock a target simply by looking at it.

    The defence system

    The SU-27P is equipped with the L-006 Beryoza (Birch) radar homing and warning receiver (RHAWS) it’s a passive ECM. The L-006 protects the aircraft in a 360° field of view. The countermeasures are located in the tail stinger and comprises build in chaff-flare dispensers. The su-27 can deploy an active ECM when the Sorbitsiya-SECM pods are loaded.

    The datalink

    Another nice feature that can be found on the flanker is its datalink. The Biryuza command link system that is fitted in the flanker can automatically direct the aircraft towards an aerial target when used in conjunction with an AWACS or a GCI centre. This enables the flanker to intercept the target in stealth mode, the target will only know that it has been tracked by the AWACS or by the GCI centre but he wouldn’t know that there is a flanker ready to fire his missiles at him.

    from aeronautics.ru data on SU30

    Radar: NIIP N001 Myech (`Slot Back’) coherent pulse Doppler look-down/shoot-down radar, detection range up to 54 n miles (100 km; 62 miles), tracking range 35 n miles (65 km; 40 miles); ability to track 10 targets and engage two simultaneously offered, but probably not available on current in-service aircraft.
    [refers to russian su30s ?]

    Flight: New navigation system based on GPS, Loran and Omega.
    Instrumentation: Integrated fire-control system enables radar, IRST and laser range-finder to be slaved to pilot’s helmet-mounted target designator and displayed on wide-angle HUD.
    Mission: Provision for fitting foreign-made airborne and weapon systems at customer’s request.
    Self-defence: SPO-15LM Beryoza 360º radar warning system; chaff/flare dispensers.

    no E3 here, so the Eagles got to find food on their own. thats
    a big departure from how they usually hunt.

    people say the Eagle has a edge in the supersonic regime due
    to its optimized for high speed design and better T:W ratio —
    — remember its a single seater 15C vs a two seater 30K. for A-2-A, the back seater may not be too useful ?

    time will tell. the results of French 2000 -vs- IAF 2000 (which has older radar) using 530D was that French were initially quite superior at BVR and were calling out BVR “kills” before the iaf pilots. They lost in WVR were iaf was very confident. towards later part of exercise the iaf 2000s had improved their bvr tactics and were getting an even exchange of shots.

    the 15C AESA + amraam is clearly a superior match in bvr to
    the 30Ks older radar and aa12. only the mki Bars maybe able to
    put it across the 15Cs.

    I think the 30Ks will lose overall.

    Kuwaitis pull out of tough Indian Navy course
    Vishal Thapar and M.A.S. Chinna
    New Delhi, January 4

    In an unprecedented incident, 10 Kuwaiti Naval officers recently deserted a training course run by the Indian Navy after complaining of ‘maltreatment’ by the hosts.

    The 10 Kuwaiti officers of the rank of lieutenant were undergoing a Bridge Watchkeeping Certificate Course conducted by the Indian Navy’s Southern Command at Kochi and Vishakhapatnam. They had completed four-and-a-half months of the six-month course when they pulled out in August. This was the first time Kuwaiti officers were attending this course.

    The Indian Navy has denied the Kuwaitis were maltreated but indicated that they were soft, expected “five-star treatment” and were unable to take the rigour of training.

    The course is rudimentary but rigorous. “It’s an important benchmark. An officer can be useful on a ship only if he is a qualified watchkeeper,” a senior Navy officer said.

    The Kuwaiti embassy in New Delhi appeared to concur with its officers that the Indian Navy’s training regimen was too rough.

    It cited the “inability” of its officers to put up with the training regimen in high seas during the monsoon as the reason for the “withdrawal”. Significantly, each of the 10 Kuwaiti lieutenants had a record of five to ten years of service.

    Indian training standards are tough. Apocryphal legend has it that even the US SEALS — the universally-known crack marine commandos — were staggered at the Indian training rigour (for their counterparts) and had described it as “inhuman”.

    The Indian Navy insists the trainees have to be “put through the paces” and that there can be no compromise on the regimen. “This is only a reflection of the high standard of training imparted by the Indian Navy,” a senior officer said. “The Kuwait Navy needs to be concerned that its officers were unable to cope up,” he pointed out.

    On its part, the Indian Navy was observing a certain leniency with the Kuwaitis, as it does with many foreign trainees.

    “Foreign personnel from certain Gulf countries under training with the Indian Navy have been provided additional residential facilities of soft furnishing and air conditioning on payment by their governments,” a Navy spokesman said.

    In the case of the Kuwaitis, they were allowed to stay in hotels on off-duty days while their ships were in harbour. The 10 officers were assigned to three Indian naval ships based at Kochi and Vishakhapatnam.

    The Navy has strongly dismissed the “maltreatment” charge. “We have been training foreigners from 28 countries since 1965. Currently, about 350 foreign personnel are being trained by the Indian Navy annually. No complaint of maltreatment has been received,” a spokesman said.

    india desired to improve relations with US in early 1990s and
    took up US offer of engine and help with the FBW in which ADA
    had zero experience. US made available the F16XL testbed and
    some indian engineers kept coming and going from lockheed to
    learn how to code the FBW. it was partly a political decision. india
    already had good relations with france. and in that timeframe IAF
    was having a rough time with the Mig29 engines following breakup of fUSSR and dislocations in the parts chain plus poor
    initial quality of the RD33 (these were finally overcome in late 90s and Mig29s returned to normal flying hrs). so nobody was keen
    on a russian engine, US was also far ahead in FBW.

    didnt Rafale prototype first fly with GE404 engine in 1988 and
    then M88-1 came along ?

    I doubt M88-1 was on the table for india in early 1990s and it
    was a new engine compared to GE404 whose base design was
    older from early 1980s and more proven.

    well the J-12 being very strategic and needing lots of new work will certainly keep SAC going – none of the others have a 5th gen project going.
    And the J-11B certainly brings more to the table than J-8 and FC-1..it is going to be PRCs premier air-to-air fighterfor next 20 years atleast.

    SAC will be around for sure.

    1980 Hong Kong ship owner C.Y.Tung’s ‘Seawise Giant’ with 564,839 DWT is the largest tanker and the largest man-made structure in the world. After just two voyages goes into layup and serves as storage vessel later on. Sold to Norway and re-named ‘Jahre Viking’. Specs: Length 1,504’, beam 226’, draft 98’, 260,851 GRT, 13 knots.

    ==> 1504 ft x 226 ft

    Nimitz class
    ==> 1092 ft x 250 ft
    ==> 100,000t full load.

    What is the empty weight of a ULCC tanker (minus the fuel)

    I’d hazard a guess the empty weight of a CVN nimitz is around
    90000t. (100ac @ 20t is still only 2000t, fuel ??)

    I dont think building large tankers is any assurance of capability
    to build large carriers , but it is one of the factors only – you have exp with large building yards and processes, plus manpower trained.

    if PRC has any ambitions of being the leading east asian or even
    a global power, building large carriers cannot be walked away from. So they had better start early …. the internal design of
    merchant ships is relatively simple, the tanks just scaling up of
    a single cell design looks like. A CVN has 100times more machinery and internal complexity spanning 7-8 deck levels ,
    classified damage control measures and so on.

    CVNs just cant be churned out the way hyundai makes merchant ships. as you can see from the dimensions even a ship 2x a 300,000t ULCC doesnt ‘dwarf’ the Nimitz just matches it in width and slightly longer in length. the Nimitz rides far more out of the water than a low-slung ULCC and towers over anything else nearby.

    DWT is weight of cargo a ship carries 300,000DWT means it
    carries that much oil. used for oil and bulk carriers.

    displacement tonnage (like 100,000 for nimitz) is used for
    navy ships.

    USS constellation = 81,000t full load displacement
    Jahre viking is only 36,000t empty it looks like from
    page 7 of below.
    http://www.australianheritagefleet.com.au/JCFullBy/crewnews3.pdf

    just as I suspected these ULCCs use far less steel and machinery
    than a CVN and are far easier to manufacture.

    not for nothing a single CVN cost $5 bil to make.
