    “Up to now, not one country of the world has been able to repeat this engineering achievement. “

    More precisely, up to now, not one country of the world has wanted to repeat this engineering achievement.

    I feel very certain that, given an actual reason to do so, Japan, Italy, France, Germany, Britain, and America could do so easily… and India, China, Brazil, and Spain have a decent shot at it.

    The main reason only the SU did so is that the benefits are marginal when compared with the alternatives… and the vulnerability of these craft.

    The “invisible/below radar” feature only applies to ground stations… airborne “look-down” radars have been able to see them very clearly since the late 1960s… and the F-15 etc have carried such radars since the late 1970s (and the Mig-31, and Tornado, and…….

    “The Yakovlev Yak-52 is a Soviet primary trainer aircraft. It first flew in 1976 and is still being produced in Romania, by Aerostar. The Yak-52 was designed originally as an aerobatic trainer for students in the Soviet DOSAAF training organization. That organization trained both civilian sport pilots and military pilots.

    Since the early 1990s and the fall of the Soviet Union, many Yak 52s have been exported to the west. Of the approximately 1,800 produced to date, most now fly in the United States, United Kingdom, New Zealand, Australia and other western countries.”

    Reminds me of the statement made in America after Dec 7, 1941… “When we are done, the Japanese language will only be spoken in Hell!”

    War de-humanizes everyone it touches… combattant and civilian alike… and that is the first thing that must never be “interpreted”.

    Whether a war, or a cause, is “right” or “justified” or not, that truth remains… everyone is part animal when killing is the order of the day.

    Maybe I’m being dim but how can aircraft with no airframe hours left be used for flight training?

    It all relates to fatigue issues.

    They have few or no combat-rated hours left (cleared for more than 4G maneuvers).

    Training aircraft are often restricted to a max of 4g, so they would be able to be flown for many more low-stress hours.

    The problem is not limited to the British Army, either.

    The RAF investigation into the accidental shoot-down of a Tornado by a US PAC3 missile in the early stages of Gulf War 2 found that the Tornado was not equipped with a NATO-standard IFF (Identify Friend or Foe) transponder.

    The RAF had asked for these transponders to be installed years earlier, but the MOD had ruled that “a lack of IFF equipment is NOT a “Safety-of-Flight” issue, therefore this equipment is given a low priority for acquisition and installation”!

    Remember that a USAF jet was also shot down the same way, a few days earlier, apparently due to a malfunctioning IFF.

    Sounds like part of the problem is lack of equipment on the British side (underlining & italics done by me):

    Gordon Brown attacked over Forces funding
    By Gethin Chamberlain, Sunday Telegraph
    Last Updated: 11:43pm BST 25/08/2007

    Gordon Brown has come under fire on both sides of the Atlantic for starving the Armed Forces of funding, leaving them struggling to fight on two fronts, in Iraq and Afghanistan.

    The Prime Minister was attacked by Liam Fox, the shadow defence secretary, and a White House adviser over ten years of “underspending”.

    He was accused of refusing to give British troops the money to defend themselves as they combat insurgents in southern Iraq and the Taliban in Afghanistan.

    The claims came as the three soldiers killed by a US jet in a “friendly fire” incident in Afghanistan were named as Privates Aaron McClure, Robert Foster and John Thrumble.

    Critics said that the men, who were hit by a 500lb bomb in Helmand, should have been protected by high-tech systems to identify them to friendly forces.

    Dr Fox said that cuts in defence spending demanded by the Treasury had left the Army unable to invest in equipment that could have saved the soldiers’ lives.

    “Gordon Brown showed no interest in the Armed Forces in his time as chancellor,” said Dr Fox. “We know what he thinks about casinos and cannabis but we have heard scarcely a word from him on Afghanistan. When it comes to people putting their lives on the line there is a deafening silence.

    “As chancellor, Gordon Brown never gave defence much priority and now the skies are black with chickens coming home to roost.”

    Since Mr Brown became Prime Minister on June 27, 13 soldiers have been killed in Afghanistan and 15 in Iraq.

    Frederick Kagan, an adviser to President George W Bush and the architect of the US surge strategy in Iraq, said the special relationship between Britain and America was under threat because defence cuts had left the Army unable to sustain simultaneous operations in Iraq and Afghanistan.

    “Britain has a lot of problems, principally that their ground forces are too small and are now paying the price,” Mr Kagan said.

    He disclosed that 3,500 US troops would have to be taken out of the surge to step into the breach when the British leave southern Iraq. “I do worry about the short-term effects on the relationship between the two countries. It will create bad feeling with American soldiers if they can’t go home because the British have left.”

    The commander of British forces in Helmand last night paid tribute to the three soldiers from 1 Bn, the Royal Anglian Regiment, who died in Thursday’s blue on blue attack. Speaking in Lashkar Gar, Brig John Lorimer said that their deaths were a tragedy that had dented morale.

    The incident is under investigation and serving officers were at pains not to lay the blame on either the American pilots or on shortages of combat identification systems designed to reduced the chances of such tragedies.

    But a powerful Commons committee and the National Audit Office have publicly condemned the Government for its failure to invest in equipment to prevent blue on blue, or friendly fire, incidents. In 2003 the public accounts committee criticised the MoD for diverting billions of pounds that should have been spent on battlefield recognition technology into other projects.

    In May this year, the committee’s Conservative chairman, Edward Leigh, said: “At the moment, pretty well the only solution to avoid being shot at by an American aeroplane if you’re in a war… is to have a great big Union Jack flying on top of your tank.”

    An MoD spokesman said: “We take the risk of fratricide very seriously and continue to invest in combat ID technologies to help prevent it.”

    The Government claims that defence spending has risen, but its critics say it has fallen compared with other areas.

    The Conservatives say that the proportion of GDP spent on defence is at its lowest since 1930. Spending on health and education has more than doubled since 1999 while defence has risen from £22 billion to £32 billion.

    Col Clive Fairweather, a former deputy commander of the SAS, said that it was cuts imposed by Mr Brown that had reduced the Armed Forces to having to call in the Americans when they needed close air support in Afghanistan.

    “It is the fault of Gordon Brown’s Treasury that the Army is under-resourced,” he said. “We don’t have enough aircraft, troops or equipment”.

    “you’re not going to be pulling a carrier into Port Stanley or Diego Garcia anytime soon like you could Sydney or Vancouver, which was my point.”

    And why not… CV-61 Ranger, which is noticeably larger than CVF will be, made a port call to Vancouver in 1986, anchoring in the harbor… and did the same at Diego Garcia in 1989!

    CVN-70 Carl Vinson visited DG in both 1986 & 1990 as well.

    Note that the lagoon of DG is a dredged anchorage capable of hosting USN CVNs… and is the permanent mooring of the 14 ships of the USN’s Military Sealift Command’s Maritime Prepositioning Ship Squadron Two!

    Add in the refueling and ship servicing facilities… and an air base with a runway long enough that it is an emergency landing site for NASA’s space shuttle, and a CVF would find DG a welcome base for supporting an extended deployment.

    Oh yes, DG is being upgraded to serve as an operating base for the USN’s SSGNs (ex-Ohio class SSBNs).

    I have run across a number of military equipment pieces that were primed, but not top-coated.

    Most commonly, they were one of the following:
    zinc chromate primer, yellow
    zinc chromate primer, red oxide
    zinc oxide primer, olive green

    “IIRC the original design of the USS Enterprise had a Talos launcher.”

    CV-63 Kitty Hawk, CV-64 Constellation, & CV-66 America were completed with 2 twin Terrier SAM launchers (1 on each stern quarter).

    CVN-65 Enterprise was also designed to carry these, but they were not fitted due to cost over-runs.

    The Terrier was the USN’s “medium-range” missile of the 1960s… and the CVs carried 40 for each twin launcher… 80 total per ship.

    “The Gripen would have been a better choice on account of its short take-off and landing capabilities, and there would still be a lot of spares commonality as it uses the same engine as the F16”

    No, it does not!

    Gripen: RM12 (license-built GE F404); 12,140 lb.s.t. (18,100 lb.s.t. with afterburner)

    F-16: Pratt & Whitney F100-200/220 (A/B/C/D); 14,670 lb.s.t. (23,830 lb.s.t. with afterburner) [later models with more powerful engines, either Pratt & Whitney F100-229 or General Electric F110]

    F-16/79: export model proposed in the 1980s (to kill off the F-20) General Electric J79-119; 12,050 lb.s.t. (18,725 lb.s.t. with afterburner at sea level [Full AB at Mach 2.0/35,000ft = 20,840 with “Combat Plus” engaged])

    J79 is a turbojet designed in the late 1950s, F100 is a turbofan designed in the late 1960s, F404 is a turbofan designed in the late 1970s.

    Not the chaps you were looking for, but another famous 1930s aviator: Wiley Post. Veteran of two “around-the-world” flights in his Lockheed Vega Winnie Mae (the second one solo). The Vega had a formed-plywood fuselage. http://en.wikipedia.org/wiki/Lockheed_Vega

    In 1934, with financial support from Frank Phillips of the Phillips Petroleum Company, Post began exploring the limits of high-altitude, long-distance flight. The Winnie Mae‘s cabin could not be pressurized so he worked with Russell S. Colley of the B.F. Goodrich Company to develop what became the world’s first practical pressure suit. The body of the suit had three layers: long underwear, an inner black rubber air pressure bladder, and an outer suit made of rubberised parachute fabric. The outer suit was glued to a frame with arm and leg joints that allowed him to operate the flight controls and to walk to and from the aircraft. Attached to the frame were pigskin gloves, rubber boots, and an aluminium and plastic diver’s helmet. The helmet had a removable faceplate that could be sealed at a height of 17,000 feet, and could accommodate earphones and a throat microphone. In the first flight using the suit on September 5, 1934, Post reached an altitude of 40,000 feet above Chicago. Eventually flying as high as 50,000 feet (unofficial, as his recording altimeter had frozen before he ended his climb, while the normal one kept working), Post discovered the jet stream and made the first major practical advances in pressurized flight.

    Note that Wiley lost one eye in a oil drilling accident before he ever learned to fly!

    He died in a plane crash August 15, 1935 in Alaska.
