S Korea 4-4E Replacement: F-15 Or F-35?

Report from flightglobal.com suggests that PAK-FA has almost no chance of being selected and Typhoon very little, so the choice is really between F-15 (offered with conformal weapons bays) and F-35. Delivery of the winning aircraft is likely to start 2016.

http://www.flightglobal.com/news/art...s-to-replace-f-4e-phantoms-362908/

What chance is there of F-15 still being in production 5 years from now? I believe Boeing was looking to shut down production in 2012 but has recently pulled back from doing so. All the same, how could Boeing keep the line open to be in a position to deliver more F-15's in 2016?

What would F-35's cost in 2016? Would S Korea have to pay a big premium over the projected price when full rate production is reached?

At least the F15 is a known quantity.

With the F35, you have apparently no idea on cost.

I guess the tension in the peninsula has given Boeing some pause... that the merest hint the ROKAF could order their F-15 Silent Eagle would send them scrambling for ways to keep the line on standby, even if it meant spending their own money.

As the article says and I quote;

"'FX-III is the USA's to lose,' said Richard Aboulafia, an analyst for the Teal Group. 'It's more than just the political dimension of a strategic relationship, which in itself is all-important to a country with a volatile and violent neighbour. It's also about shared logistics, training and doctrine.'

He cited a number of advantages for the F-15SE. 'It's got commonality with South Korea's existing fleet, a degree of stealth for the opening stages of a conflict and plenty of payload, which is important given the nature of the threat. Its only drawback is that it doesn't have all the qualities associated with the F-35.' He added that the F-35 offers a close relationship with the USAF for years to come, 'and the world's most modern air combat system [excepting the F-22].' He noted, however, that the F-35 cannot match the F-15SE on payload. 'The only other problems with the F-35 concern uncertainties about cost, timing and industrial benefits,' he said. 'I'd give the two US planes an equal chance.'

Boeing lauds the F-15SE's payload, which it claims is the highest in the competition, as well as a unique 'stealthy-when-needed' feature. In the early stages of the conflict, when stealth is useful for countering enemy air defences - given the decrepit state of the North's air force, the air-to-air mission does not seem to concern contestants - the F-15SE would operate with conformal weapons bays that help reduce the aircraft's radar cross-section.

Following the attainment of aerial supremacy, stealth would no longer be a major requirement, said Boeing. It would take three hours to trade the F-15SE's weapons bays for conformal fuel tanks, creating what Boeing refers to as an F-15K+ configuration, which is optimised for heavy loads of precision weapons. Boeing claimed this heavy configuration is ideal to efficiently destroy hardened targets in North Korea. The canted tails of the F-15SE allow for two additional weapons stations on the F-15SE's wings as compared with previous versions of the fighter."



If money would be an object, Boeing still has their regular Slam Eagles, or Super Hornets as a more economical one-for-one replacement for the retiring Phantoms.

The F-35's best chance here is if South Korea also views FX-III as a foil to China's J-20 and Russia's PAK-FA.

IMO, the ROKAF is the perfect candidate for the F-15SE. They could offer to pay the development costs (or some), in exchange for a deal like the UAE on the Block 60 F-16's. In addition to licensing / manufacturing offsets, they could receive a premium on any other F-15SE's that Boeing sells. And I suspect that a F-15SE could be way more successful then the F-16 Bk 60's.

Is there much of a market for F-15's now? Saudi Arabia. Who else might be in the pipeline?

Save for the "outdated" bit, you could probably say the same for the F-35.

Well, if the ROKAF were to order the F-15SE, development would need to begin almost immediately, and the prototype built soon for flight and weapons testing. Once those are approved the production would need to begin in 2013 fir a 2016 delivery date.

I could see Singapore ordering some F-15SEs to go with their F-15Ss they are getting now. Once Australia realizes the mistake they made ordering the F-35A, I think they will look at the F-15SE. There would be some other ME countries that could order it, along with Japan. Columbia might be the first South American country to order it to counter the new fighters ordered by Venezuela.

This is speculation. No one in their right mind would go for a paper airplane like the Silent Eagle when the JSF is almost done with their testing phase. IF the SE was in test flight mode like the JSF then I'd agree, but I don't think the Aussies will want to order more Super's to wait another two decades for SE development.

However, compared to F-35, which is in the middle of flight testing, it is still a long ways off. It is likely that the USAF would allow a major non-NATO ally such as South Korea to cut ahead and get earlier delivery slots for the F-35 if the Pentagon wants to defer some F-35's for budgetary reasons.

Singapore is a Security Co-operation Participant in the JSF project; it is highly likely that Singapore will buy F-35's.

They were discussing a parallel production line for Japan if they chose the F-35, and Turkey planned local production as well. So it should not be a problem for Korea.

Actually, there is a F-15SE prototype flying now. It is the #1 F-15E (USAF tail # 86-0183) that was modified to the F-15E1 configueration. It has been flying since mid 2010 and has one CWB installed in place of one CFT. I don't think it has the canted tails, though.

Perhaps, at least for the EA-18G/H. Don't forget the RAAF will have only 5 KC-30As, so combat aircraft that don't require refueling, or just one refueling free up the tankers for other combat aircraft. The F/A-18Fs of the RAAF have a combat radius of 390 nm, the F-15SE has double that at 800 nm. That means the F/A 18Fs will need at least 2 refuelings per combat mission, and the F-15SE may not need any refuelings, or it may need just 1.

It's not a F-15SE. Boeing is making bigger modifications as part of their F-15SE beyond canted tails and CFT's; they are talking about major structural changes to lighten the F-15SE so it can regain lost range, and also redesigning the fly-by-wire system and electronic warfare suite.

Correct, the F-15E1 is only flight testing the CWB design. It is still officially a F-15E. There have been no F-15SEs built yet, nor has the design been 'frozen' yet.

With the asking price for the F-15SE being pegged at a cool $100 million dollars, excluding any potential cost overrun because the aircraft hasn't been developed yet, it might make more sense to go with F-35 as the price will go down with time.

It appears Boeing will indeed be spending its own money to keep the F-15 line open.....

http://www.flightglobal.com/news/art...anticipation-of-saudi-deal-363960/

Quote:
"Boeing is self-funding production of F-15E strike fighters in the expectation that Saudi Arabia may sign a contract at some point before November 2012, said chairman, president and chief executive Jim McNerney.

McNerney's comments provide some insight into the status of an opportunity to sell 84 F-15SA fighters to Saudi Arabia, along with radar and weapon upgrades for the country's existing F-15 fleet.

The US Defense Security Cooperation Agency notified Congress on 20 October 2010 that Riyadh had requested the possible sale, but the deal has remained unsigned after more than a year."



This could have positive repercussions on Boeing's efforts to sell the Silent Eagle for KFX-III to the ROKAF.

Quote:
"This literally slipped right past us last week in Seoul. Buried in the Korean-language F-15SE Silent Eagle brochure, which we brought home as a souvenir, is an image revealing Boeing's concept for South Korea's KF-X fighter. It was so sneaky we didn't even spot it until it was pointed out to us by an alert blog reader, who had downloaded the same brochure on Boeing's web site. Yes, we are ashamed.

Judging by this image, Boeing is offering a single-seat fighter with a V-tail and an internal weapons bay. We detect a passing resemblance to a snub-nosed F/A-18. It's difficult to determine whether the image shows one or two engines, but South Korea's preference is clearly the latter."



On the other hand, South Korea's pursuit of an indigenous stealth fighter may bring that acquisition's prospects into question.....

Quote:
"South Korea needs help developing KF-X. Its industry feels up to the challenge of developing the new fighter's flight controls, aerodynamics, sensors and weapons. But it wants an industrial partner to transfer technology for the engines, sensor fusion software and systems integration. This presents a certain dilemma for potential US partners. How much do Boeing and Lockheed Martin give up for a piece of the KF-X programme, knowing South Korea's fighter ambitions means losing a historically reliable customer and possibly creating a future competitor?"

Update:

Boeing is setting the stage for what may be the F-15's last hurrah.....

http://www.flightglobal.com/news/art...agle-tests-for-south-korea-367495/

Quote:
"Boeing is poised to launch a new series of ground, windtunnel and flight tests on several key features of the F-15 Silent Eagle proposed for South Korea's competitive F-X III contract.

Windtunnel tests will start by March or April on a scale model of the F-15SE with conformal weapons bays, said Howard Berry, Boeing vice-president for sales. The weapons bays, which are modified conformal fuel tanks, allow the F-15 to store weapons internally and lower the aircraft's profile to radars.

Flight testing will begin late in the fourth quarter of 2012 or early next year of an 'advanced international F-15', Berry said. The new-build test aircraft will feature the cockpit systems, digital electronic warfare system and sensors unveiled with the Silent Eagle concept in March 2009.

Boeing will also start windtunnel tests to determine the aerodynamic performance of various angles for the Silent Eagle's proposed canted vertical tails, Berry said.

The company's original concept featured tails canted at 15º as a stealth technique. The canted tails allow the aircraft to bank up to 15º on either side without presenting a 90º angle to airborne radars."



It seems a bit tardy to be doing the wind tunnel tests for the Silent Eagle just now...long after they broached the idea, and test-fired a missile from the converted CWB. Ditto for the canted tails. Looks as though they're trying to squeeze the last drop of revenue out of the Eagle before they partner with the South Koreans for their indigenous stealth fighter design. LockMart would love that.

I was in Korea for work shortly after the Japanese decision in favor of the F-35, and virtually everyone I spoke to with links to the ROKAF and government said Korea would likely follow the Japanese lead. This apparently has historical precedence that from an ego perspective Korea tends not want Japan to have something better or more advanced then it.
Also the fact that the USAF is onboard with the F-35, and at some point those will be based in Korea is a big plus from commonality and operational vantage.

I really believe Boeing is going to have a hard time with any F-15 variant they try to push at this stage.

"South Korea's Defense Acquisition Program Administration (DAPA) has issued a request for proposals for its F-X III fighter requirement, paving the way for the acquisition of around 60 fighters.

The submission guidelines were issued at a meeting in Seoul yesterday. The contenders for the requirement are the Boeing F-15 Silent Eagle, Lockheed Martin F-35 Lightning II and the Eurofighter Typhoon."



The pressure is on the 4.5 Gen fighters to prove that they still got (or will have) what it takes to win vs a true 5thG entry in a contest that seeks a defender against the Chinese J-20 and Russian PAK-FA, and their other contemporaries around as well.

Fortunately for Rafale, it now only needs to hurdle the relatively less brutal battles on the bargaining table, and possibly in court for any protest that could be filed after its big victory.

"The United States Air Force (USAF) variant of Lockheed Martin’s F-35 will likely fail to meet two of the Korean Air Force’s key requirements — the ability to carry weapons externally and fly at Mach 1.6 (1,930 kilometers per hour) or faster, an industry insider said Tuesday.

He pointed out that the Korean military has clearly outlined the two key features as compulsory requirements in its request for proposal (RFP) released Jan. 30.

'The maximum speed of the F-35 Lightning II, which is still under development, is Mach 1.6, the bare minimum the Air Force has stated as a mandatory requirement,' the insider familiar with the RFP said."



But LM has a nice comeback.....

"He pointed out that countries such as China and Russia are developing stealth aircraft, the Chengdu J-20 and Sukhoi PAK FA, which creates a requirement for aircraft with stealth technology, integrated sensors, and connectivity.

'To make a stealth aircraft, you need to carry all the sensors and weapons internally to make the aircraft very smooth,' he said. 'You have to align the edges of the airplane, bury the engines so you can't bounce a radar beam off the front of them. This means you can't add stealth to an existing platform. Stealth isn't something you can retrofit'."


http://cde.cerosmedia.com/1H4f3a42ee676bf012.cde


At the moment, I can't find the report saying DAPA is dropping the compulsory requirements. Anyway, nice to have a chance for another round of debates here re partial vs total stealth.

That is a terribly written article, I am not sure why they even published it other than to add to the JSF hysteria.

Will the F-35 fly at M1.6? Sure it will, it already has and there is no evidence that the aircraft won't reach that speed in operational service. It may not get too far beyond that but the point is a bit moot as none of the three contenders for the contract can reach M1.6 without burner anyway, especially with any meaningful payload.

The second key feature on being able to carry external ordinance is also odd. The JSF will carry external ordinance, if it didn't that would be a valid reason to cancel the entire program! The JSF development schedule might struggle to meet the South Korean timeline for external weapons capability though which is fair enough.

The end of the article says the following though,"Other industry officials, however, refuted Howard’s claim, saying the development of external pylons not only reduces the aircraft stealth capabilities, but also requires a fundamental change in the aircraft design, which the USAF is not willing to pay for."

Shouldn't be a surprise on compromising the stealth capability, as it would for each of the contenders and every other aircraft including the F-22, stealth UAVs and the starship enterprise and the JSF has never been advertised as able to carry external payloads in stealth mode. External pylons also won't require a fundamental change and are already within the planned development cycle for all three versions of the aircraft.

I wouldn't trust the "other industry officials" as having any idea what they're talking about if above is what they actually said!
