Re: ADA LCA Tejas Mark-II

This is why you should read what I post.

1) SH with tanks will out-range F-35, in both range and combat radius. We are talking about 10.5 tonnes of fuel on SH vs 8.8 tonnes of fuel on F-35C.

2) The reason why I give 3 tanks to SH while none to F-35 is for the simple reason that the F-35 will lose a lot of its advertised capability.

If you combine points one and two you will notice two things. SH's advertised capabilities give it greater range and radius. F-35s advertised capabilities do not allow it the advantage of EFTs which will render it less capable at the cost it is being procured for. If you really want to fly F-35s with tanks, then USN is better off replacing SH Block 2s with SH Block 3s with EFTs, CFTs and EWPs at a lesser cost instead of buying the more expensive F-35C. That will give you more range at lesser cost.

3) USN will want an aircraft that can match SH's flexibility with F-35s capabilities. F/A-XX is the answer, in any form, be it LM's F-35C Mk2 or Boeing's SH replacement program. LM can always make the F-35 larger than it is. My point being, F-35C isn't a direct replacement for SH.
1. About 1/4 of external fuel is lost to drag alone, and it's even worse for the Shornet due to toe-out of external stores (a cheap fix for an early design error). Sorry, but the F-35 still has it beat range-wise for all practical purposes.

2. Again, tanks can always be dropped if required. Also, don't be surprised if you eventually see F-35Cs flying with external stores most of the time. Of course, when it first enters service, it will likely be kept in its VLO configuration; but as it becomes more common, the flexibility advantages of external fuel for routine operations will change that. And as for costs, saving money isn't much of an advantage with an old fighter design. Hungary has been trying to sale its Mig-29s for two rocks apiece and still can't find a buyer.

3. I never said the F-35C is currently slated to replace the SH (it isn't as the SHs still have too much useful life to simply throw away and replacing the ABCD Hornets alone will take long enough). However it it still has the advantage in practical range (along with other capabilities) and the USN is unlikely to get a clean-sheet design in the F/A-XX's stated timeline.

The figures I quoted are supposed to be official figures that take into consideration the loss due to drag.

SH does better when it comes to drag compared to Hornet.

3. I never said the F-35C is currently slated to replace the SH (it isn't as the SHs still have too much useful life to simply throw away and replacing the ABCD Hornets alone will take long enough). However it it still has the advantage in practical range (along with other capabilities) and the USN is unlikely to get a clean-sheet design in the F/A-XX's stated timeline.
Only 260 F-35Cs have been ordered and they will replace 400+ Hornets. There are still 565 Super Hornets and some 100 odd Growlers that need replacement. So USN isn't planning a bird for bird replacement with F-35 alone. So 260 F-35Cs vs 1000 Hornets and Super Hornets. The math doesn't add up.

Also, don't mistake my stand of saying the SH's EFT capability diminishes F-35s other parameters. After all, the reason why F-35 has so much internal fuel is only to replicate the Flanker. The Flanker has plenty of internal fuel and has little need for EFTs, thereby saving fuel by diminishing drag. Still fuel tanks help and they definitely remove a lot of the F-35s RCS advantage. No point doing that unless you have proper air superiority in the region.

Israel Will Be First International Customer To Fly F-35s



PARIS/TEL AVIV – Though late to sign on to the network of nations purchasing the F-35 Joint Strike Fighter, Israel will be the first international customer to operate the fifth-generation fighter.

"Israel will become the first non-U.S. operator of the F-35 in the world," said Steve O'Bryan, Lockheed Martin's vice president for F-35 program integration and business development in an interview at the Paris air show. The first F-35I combat squadron is expected to achieve initial operational capability in 2018.

Eight other countries have already committed to the program with firm contracts.

"The F-35 fighters going into service with these users will use different initial versions that will be upgraded later into the latest version, as it becomes available," O'Bryan said. That mean F-35s will be tailored to individual nations, he says.

"Specific capabilities developed for certain users will remain exclusive, and open to other users only with the original user's consent. For example, the software blocks pertaining to the Norwegian anti-ship missile will not be available to other F-35 operators except Norway, unless it decides to sell those missiles to one of the F-35 users. The same goes to the Rafael Spice 1000. Similarly, the advanced electronic warfare, data links and specific software modes developed for the Israeli air force will remain unique to Israel and not delivered to any other user. These capabilities will also be fully integrated with the aircraft capabilities, adhering to the stealth characteristics of the aircraft, particularly, at specific apertures cleared for the Israeli systems integration in the lower fuselage and leading edge," he said.

The first Israeli pilots plan to arrive at Eglin AFB, Fla., for training on the F-35A in early 2016. The first aircraft is tentatively set to be delivered to the Israel air force toward the end of that year, and arrive in Israel in 2017.

These F-35Is will be produced under Low Rate Initial Production (LRIP) lots 8, 9 and 10. By that time, all 19 aircraft included under the $2.75 billion order will be delivered to the IAF under the current five-year plan. A follow-on order for more F-35Is is expected in 2018, under the next five-year plan. As the new fighter enters full-production rate, volumes are expected to increase, leading to proportionally lowering cost, expected to drop below $85 million in then-year dollars.

Financing of this follow-on procurement is already under discussion with the U.S. Jerusalem is seeking creative ways for Washington's agreement to guarantee payment for these planes, including the foreign military sales budget allocated annually to Israel. If this concept is approved, Israel will be required to pay for the interest but will be able to commit willingly to follow-on orders and receive the second squadron immediately after the first is delivered.

"With the F-35 Israel is expected to receive the AIM-9X short-range air/air missile (AAM) and the Raytheon AIM-120 AMRAAM Beyond Visual Range (BVR) AAM," O'Bryan added. The F-35 currently carries the Raytheon AIM-9X Block at the outboard under-wing stations, in non-stealth configuration, as the current Block I missiles cannot be carried internally. This shortcoming will be corrected in Block II, which is to follow soon.
Nevertheless, the optimal weapon carriage for the F-35 comprises exclusively the AMRAAM missiles, enabling the fighter to maximize its "see-first, shoot-first, kill-first" strategy. The next generation BVR-AAM will offer both active and passive guidance techniques, offering effective intercept ranges in excess of 100 km. This makes part of the argument not to include the Rafael Python V missile in the aircraft configuration; the next generation Python VI will be designed to fit the new fighter. Yet, according to IAF sources, a decision whether to use a derivative of the Stunner or a brand-new AAM has yet to be made.

F-35s are prepared to fight air combat as a "networked formation," sharing all information between all members at all time. The data link used for this process, called MADL, will also be available to all F-35 operators. In addition, Harris Multi-Function Advanced Data-Link (MADL) terminals could be installed on certain support elements, to extend information sharing and update the data available to the stealthy F-35 formation. In addition, the F-35 is now offering Link-16 connectivity and would obviously include a satellite link as well, providing secure, low-probability-of-detection communications on extended range missions.

In August 2012 Lockheed Martin received a $206 million award from the U.S. Navy Naval Air Systems Command, covering the development and integration of Israeli systems in the F-35A. Part of a larger package, the integration support agreement with Lockheed Martin covers a $450 million program to enhance Electronic Warfare (EW) equipment on the F-35, and integrate Israeli-unique systems beginning in 2016.

"The advantage of this F-35 for the Israel air force is not about higher performance or a specific weapon capacity, but the ability to understand the battlespace, identify, locate targets from standoff range and neutralize them before being engaged," Brig. Gen. Hagi Topolanski, Chief of Air Staff and Deputy Israeli Air Force Commander, told Aviation Week in a recent interview.

"These capabilities are meaningful in dealing with modern fighter aircraft and advanced SAMs. While the F-35 has its limitations, it can take on and win against any threat currently available in-theater. Its ability to independently collect, assess and process a battlespace situational picture, and strike those targets by itself, from standoff range, is providing a qualitative edge over anything the enemy can confront with, in the foreseeable future."

Israel insisted upon a number of requirements throughout the procurement negotiations on the F-35I. Those included the adaptation of the baseline F-35A including all its systems, to the Israeli air force's operational environment, which will require some necessary additions.

"Our F-35I will be equipped with our specific networks, armament and electronic warfare, among them the Spice autonomous EO guided weapon. It will also carry the AIM-9X2 air-to-air missile, which will become the first platform in the IAF to employ this advanced air-to-air missile. We also plan to continue and pursue the development of future air-to-air missiles; we are still evaluating the cost/performance trade-off between a common air-to-air and air-to-ground missile and a dedicated AAM design," Topolanski explained. "Assuming the F-35 will offer the capabilities it is planned to deliver, it will bring a new dimension to air battles as we know today."

One of the advantages of the F-35 is the aircraft's ability to fly long-range missions with internal weapons, accelerate faster and maintain higher speed, compared to current F16s or F-15s or any of the opposing force combat aircraft (flying with internal fuel).

To further extend the F-35's range, Lockheed Martin is exploring an innovative concept from Israel, of using unique drop tanks, developed by Elbit Systems Cyclone. Designed in a similar concept to the F-22 under-wing drop tanks, these tanks, each containing 425 gal. of fuel, will use special attachment pylons that would completely separate from the wing, regaining full stealth capability after separation. An additional 900 gal. of fuel will significantly extend the F-35I range, enabling the IAF to operate its new stealth fighter at the "outer ring" of operation without mandatory aerial refueling.

Pentagon considers cancelling F-35 program, leaked documents suggest


Leaked documents from a Pentagon budget review suggest that the agency is tired of its costly F-35 fighter jets, and has thoughts about cancelling the $391.2 billion program that has already expanded into 10 foreign countries.\\

The F-35 program is the Pentagon's most expensive weapon system. A fleet of 2,443 aircraft has an estimated price tag of $391.2 billion, which is up 68 percent from the projected costs measured in 2001. Earlier this year, Air Force Lieutenant General Christopher Bogdan, the F-35 program manager, condemned the manufacturer for "trying to squeeze every nickel" out of the Department of Defense.

Lockheed Martin, DOD Agree on F-35 Cost Reduction of up to 8%



The U.S. Department of Defense and Lockheed Martin have reached an agreement in principle for the next two F-35 Lightning II aircraft production contracts, reflecting up to eight percent cost reduction compared to current prodyction prices agreed upon in December 2012.

Low-Rate Initial Production (LRIP) lots 6 and 7, which covers the production of 71 aircraft. The two agreements reflect the continued reduction in the pricing of the F-35 aircraft. The contracting effort spanned six months from proposal to settlement. A decrease in F-35 LRIP 6-7 unit costs, coupled with negotiating lower prices on a number of other smaller contracts, will allow the DOD to purchase all the aircraft originally planned, including those that were in jeopardy of being cut due to sequestration budget impacts.
Cost details will be released once both contracts are finalized; however, in general, the unit prices for all three variants of the U.S. air vehicles in LRIP-6 are roughly four percent lower than the previous contract. LRIP-7 air vehicle unit prices will show an additional four percent reduction. The LRIP-7 price represents about an eight percent reduction from the LRIP-5 contract signed in December 2012.

"These two contracts represent a fair deal that is beneficial to the government and Lockheed Martin," said Lt. Gen. Chris Bogdan, F-35 Program Executive Officer. "Improving affordability is critical to the success of this program, and by working together we were able to negotiate a lower cost F-35. There is still work to be done, but these agreements are proof the cost arrow is moving in the right direction. We will continue to work with industry to identify areas for savings in future production contracts."

The new contracts will also include the first F-35s for Australia, Italy, Norway, and the fourth F-35 for the United Kingdom. In addition to procuring the air vehicles, these contracts also fund manufacturing-support equipment and ancillary mission equipment.

Deliveries of 36 U.S. and partner nation aircraft in LRIP-6 will begin by mid-2014 and deliveries of 35 U.S. and partner nation aircraft in LRIP-7 will begin by mid-2015.

"At the start of these negotiations, the F-35 Joint Program Office and our F-35 team jointly committed to conduct LRIP-6 and -7 negotiations in an efficient manner that leveraged all we achieved from the LRIP-5 contract," said Lorraine Martin, Lockheed Martin F-35 Vice President and General Manager. "Today's agreement reflects our collective JPO/LM delivery on that commitment. We know how critical aircraft production is to meeting our services' Initial Operational Capability dates, beginning with the Marine Corps in 2015, and we're committed to making that happen."

The LRIP-6 and -7 aircraft will join the 95 F-35s contracted under LRIPs 1-5. To date, 67 F-35s (including test aircraft) have been delivered from Lockheed Martin's production facility in Fort Worth, Texas. The U.S. and eight partner nations plan to acquire more than 3,100 F-35 fighters. Israel and Japan have also announced plans to purchase the jet under Foreign Military Sales agreements.

The agreement in principle reached between the Government and Lockheed Martin are for air vehicles and do not include the propulsion systems. The LRIP-6 engine contract is currently being negotiated between the Government and Pratt & Whitney.

F-35C Completes First In-
Flight Refuel With USAF
KC-135



NAVAL AIR STATION PATUXENT RIVER, Md., Aug. 23, 2013 – On Aug. 20, an F-35 Lightning II carrier variant (CV) refueled from a U.S. Air Force KC-135 for the first time. With the completion of this test, the F-35C joins the A and B models in proving that all three variants of the F-35 can be refueled from a common tanker platform, despite different methods. The aircraft, known as CF-1, was piloted by Lt. Col. Patrick Moran. Earlier this month, the Strike Fighter Squadron (VFA) 101, the Navy's first F-35C Lightning II carrier variant aircraft squadron, completed its first flight at Eglin Air Force Base, Fla. Headquartered in Bethesda, Md., Lockheed Martin is a global security and aerospace company that employs about 116,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The corporation's net sales for 2012 were $47.2 billion.

When The F-35 Is Too Hot To Handle

Over the last five years, testing of the STOVL (vertical takeoff and landing) or "B" version of the new American F-35 fighter showed that its F135 engine, the most powerful to ever be used in a fighter, generated enough heat to damage carrier decks. The F-35B engine heat effect was reduced by adjusting of the F135 exhaust (dispersing over a larger area). This, however, did not eliminate the other heat related problems. Components beneath the deck required better protection from the higher heat levels. On the smaller helicopter carriers (like the Wasp class) it was found that many nearby systems on the much smaller flight deck could be damaged by an F-35B landing or taking off too close to things like weapons (Phalanx and the like), antennas, aviation fuel outlets, fuel pipes, life rafts, life rails, safety nets, some electrical gear, and most other equipment that was safe to leave near the older AV-8B Harrier STOVL. So these items have to be either moved or provided with more heat protection.

The basic problem was that the F-35B is larger, and puts out more engine blast, than the current AV-8B, which has been in service since 1969. That early version was used mainly by the British Royal Navy and the U.S. Marine Corps. It was an 11 ton aircraft (7 tons when taking off vertically) that carried about two tons of weapons. In the 1980s, a more powerful 14 ton version was developed, which could carry three tons of weapons. That generated more heat, but not enough to be a problem. The F-35B, which will replace the AV-8B, is a 27 ton aircraft that can carry six tons of weapons and is stealthy. In vertical takeoff mode the F-35B will carry about twice the weapons as the Harrier and have about twice the range (800 kilometers).

On land the F-35B also causes heat problems with the PSP (Perforated Steel Planking) used for rapidly constructed airfields. PSP is one of those prosaic innovations that everyone takes for granted. PSP is perforated metal matting that is used to rapidly create all-weather airstrips that can handle jet fighters and helicopters.
