New 150million combat jet is banned from flying in bad weather because it could EXPLODE
Daily Mail ^ | 20 January 2013 | James Rush

Posted on 01/20/2013 1:04:14 PM PST by spetznaz

It's considered to be the world's most sophisticated superfighter jet, but Britain's new £150million combat aircraft has been banned from flying in bad weather for fears it could explode.

Engineers working on the F-35 Joint Strike Fighter have found the jet's fuel tank could explode if hit by lightning.

According to reports, the aircraft, which is hoped to enter service for both the RAF and the Royal Navy in five years' time, has also been made more vulnerable to enemy attack than the aircraft it is set to replace, after its weight was reduced in an attempt to increase fuel efficiency.

The F-35 may eventually prove all skeptics wrong, but the bad news keeps on coming. More bad news for the F-35, including:

- until a device in the fuel tank is redesigned, test-flying within 25 miles of thunderstorms is 'not permitted'.

- a fault in the design of the fuel tank which means it is unable to rapidly descend to low altitude.

- a handful of cracks discovered during examinations by the United States Air Force and the aircraft's manufacturer Lockheed Martin.

- The report states: 'All of these discoveries will require mitigation plans and may include redesigning parts and additional weight.'

The F-35 is a camel: a mouse built by government committee.

And as you said: just when it could not possible get worse, it gets worse.

Until the chinese and the russians and pretty soon the japanese/koreans caught up, and the remaining, flying F22’s are given to the muslim brotherhood.

“The F-22 WAS a pretty good aircraft ....”

I remember reading in Aviation Week in the ‘80’s that in the 2020’s each fighter jet would cost hundreds of millions. Well, the F-22 is 361 million a copy. That’s the purchase price. Maintaining them for 30 years will greatly increase that cost. We obviously need fighter aircraft. But maybe, just maybe, we’re going about it all wrong. Perhaps they should be a combination of Artificial Intelligence and remote control. That ought to cut the cost and the risk in half. Maybe they should be bought in a multi-year contract that’s funded for the entire contract rather than one year at a time so Congress can get lobbyist funds for their campaigns. Perhaps we should get the military out of the day-to-day engineering as they change what they want moment to moment. Or, never define what they want, as in the case of FCS. Maybe we need to incentivize companies differently. FCS was incentivized based on how much they spent. If their spend plan stayed on target they got extra money. The program’s design fell behind, but, they certainly spent the money on time.

Not to worry ... with sequestration pretty much everyone involved with the F-35 will be looking for another job. Taxes will go up, our military will the logistical nightmare of supporting far more specialty aircraft than necessary, and we will grow more incapable of defending our nation.

But - at least we aren’t entirely racist - we have a half-black president.

Plus very different intended roles. The F-22 was the replacement for the F-15. The F-35 is a plane that is supposed to do every thing the F-16, F/A-18 and the Harrier do.

Fuel Efficiency = Range. It’s range as designed is extremely poor, so they’re desperate to do anything to increase the range.

Agreed. Range isn’t great but there we have it. We have put all our chips on this jet so one way or the other we are going to have to make it work for us.

Let’s see how its doing in ten years.

Our procurement is a broken system, The F22 is too big, too stealthy,too fast, too expensive.
Why do you need stealth over friendly territory? was it built to last in Alaskan conditions? etc

Look at the rear wheels. They’re bent out. Either there’s too much weight on that thing, or it needs a wheel alignment. My cousin Steve could do it for $200. He’s got one of those laser alignment gizmos.

Absolutey correct on the first point. DOD adds/changes with abandon and then gripes because neither original objective nor the add-ons work like they'd dreamed. The other is called 'cost plus incentive fee', a great concept except that the guy responsible for holding price down gets to evaluate performance toward that incentive.

Well, between his tax-payer financed vacations and world travels; the odds are that he won't be home when the bad news arrives. Besides, he's already publicly stated he would not use the Nuclear stockpile even if we were attacked with nukes first.

And we both know that he will state that somehow, in some way - it was all our fault.

Congress is more at fault than even the contractor for that price tag. If we had bought them in the numbers we actually needed the overall investment wouldn't have gone up that much and consequently the per unit cost would have been far less. Instead the ordered a few here and a few there then killed it.

If congress bought cars the same way they buy jets they would cost almost as much.

What’s so special about that fighter?>>>>>>>>>

It operates in -50F weather, is STOL, will fly off dirt or ice/snow strips and has fully portable ground support mobile units ( fuel , maintenance, ordnance and operation, requires no specially tained servicemen to combat service the A/C in 10 minutes). A small crew with a dozer and chain saws can make a strip for the A/C in a few days, or alternately a crew with chain says and a water pump in freezing environments.

Four basic air to air modes: Track While Search, Priority Target Tracking gives higher quality tracking for multiple targets, Single Target Track gives highest quality data, Air Combat Mode for short range search and automatic target capture.

Targeting pod: Litening, with FLIR and laser designation.

The Gripen’s built-in armament consists of a single Mauser BK-27 27 millimeter cannon, housed in a fairing on the aircraft’s belly, offset to left to the rear of the engine intake. Given the aircraft’s relatively small size, it generally carries guided weapons to ensure maximum combat effectiveness.

Possible external stores include:

Air to air missiles (AAMs). The primary AAM is the Raytheon AIM-120 AMRAAM, and the Gripen’s PS-05A radar can guide four of these weapons simultaneously. Sweden is the only nation approved by the US to perform flight tests of AMRAAM, and Swedish AMRAAMs have minor modifications to fit Swedish specifications. Other possible AAM stores include the French Matra Mica; the British Aerospace Sky Flash, built in Sweden as the “Rb-71”; and the Anglo-French MBDA ramjet-powered Meteor BVRAAM or German BGT IRIS-T AAM, now in development. IRIS-T is a short-range heat-seeking AAM with “off-boresight” capability. The Flygvapnet intends to obtain the IRIS-T to replace Swedish-built Sidewinders.

Antiship missiles, such as the SAAB RBS-15 turbojet-powered sea-skimming missile. A precision land-attack version of the RBS-15 is now in development.

Air to surface missiles, such as the Raytheon AGM-65 Maverick, built in Sweden as the “Rb-75”, as well as the “BK (BombKapsel) 90 Mjoelnir” guided gliding submunitions dispenser, also known as “DWS-39”. The Mjoelnir was developed by Daimler-Benz Aerospace (now part of EADS), with the Gripen as the first intended flight platform. Of course, dumb bombs and unguided rocket pods have been qualified as well.

The aircraft is controlled by a digital fly-by-wire (FBW) system with triple redundancy and an analog backup. The analog backup system provides a simple, reliable capability, and is automatically activated if two of the three digital FBW systems go down. The pilot can also activate the analog system with the push of a button. The Gripen was designed from the outset to use the FBW system, which was evaluated on a modified Viggen. The FBW system compensates automatically for the degree of instability built into the Gripen to increase its maneuverability. The FBW system also allows the aircraft to adapt to combat damage, for example using differential control of the canards to fly the aircraft if the ailerons are disabled.

The Gripen pilot can switch operational role in flight.

One Gripen can provide radar sensing for four of its colleagues, allowing a single fighter to track a target, while the others use the data for a stealthy attack. TIDLS also permits multiple fighters to quickly and accurately lock onto a target’s track through triangulation from several radars; or allows one fighter to jam a target while another tracks it; or allows multiple fighters to use different radar frequencies collaboratively to “burn through” jamming transmissions. TIDLS also gives the Gripen transparent access to the SAAB-Ericsson 340B Erieye “mini-AWACs” aircraft, as well as the overall ground command and control system. This system provides Sweden with an impressive defensive capability at a cost that, though still high, is less than that of comparable systems elsewhere.

The Gripen can take off and land in less than 600 meters (2,000 feet). Once deployed to a road base, the Gripens are serviced by a ground crew of six, including one highly trained specialist and five minimally trained conscripts. A service team can refuel and rearm a Gripen in ten minutes. The Gripen features an auxiliary power unit (APU) to reduce its dependence on ground systems, and the fighter’s onboard digital systems include “built-in self-test” capabilities that can download diagnostic data to a tech’s laptop computer. Service doors to critical systems are at head level or lower, allowing easy access by technicians. Pilots using the Gripen flight simulators have performed simulated carrier landings, without an arresting hook; it seems a bit unlikely that this will ever be done in practice, however.

The operational cost of Gripen is 50 per cent lower than any other aircraft in its class that is currently, or planned to be, in service. It is twice as reliable and easier to maintain than its competitors.

Features under development for future Gripens include:

An electronically-scanned array (AESA) radar based on the PS-05/A, now being developed by Ericsson. An AESA consists of an array of programmable “transmit-receive (TR)” modules that can operate in parallel to perform separate or collaborative functions, performing, for example, jamming and target acquisition at the same time. The AESA will provide enhanced multimode capabilities, as well as extended range for beyond visual range missiles. It is scheduled for introduction in the 2005:2010 timeframe.

Improved defensive countermeasures, including new towed decoys and missile and laser warning systems.

The “OTIS” infrared search and track (IRST) system now under development by Saab Dynamics and being tested on a Viggen. OTIS will provide multiple modes for both air to air and air to ground combat.

The Thales “Guardian” helmet-mounted display (HMT), now being evaluated on the Gripen for cueing the IRIS-T and other smart weapons.

The Gripen’s digital architecture makes software upgrades straightforward, at least as such things go. Possible software improvements include new radar and datalink modes; a new terrain-referenced navigation system; and a fully autonomous precision landing-guidance system. In the long term, SAAB is looking at a new engine, such as the General Electric F414 or a thrust-vectoring version of the EJ2000 engine used on the Eurofighter; conformal fuel tanks or a fuselage stretch for greater range; a wide-angle HUD; a binocular helmet-mounted display; a direct voice-command system; and an advanced missions support system.

Currently, only the SWAF has the Gripen in active service but during 2005 South Africa, the Czech Republic and Hungary will take 21, 14 and 14 Gripen into service. Hungary and the Czech Republic will get fully NATO-adapted Gripens.
