South  Korea's efforts to equip its airmen with hundreds of high-tech fighter  aircraft, including stealth jets, are apparently being stuck in limbo in  the face of budget restraints and uncertainty over candidate planes and  the country's fighter procurement methods.
Following  the previous two phases of F-X projects for 60 F-15K aircraft built by  the U.S. Boeing Company, the country is scheduled to open the bidding  process next year for another batch of foreign fighter jets, probably  stealth aircraft.
The F-X program is aimed at introducing 120 high-end warplanes by 2020 to replace the aging fighter fleet of F-4 and F-5 planes.
On top of that, the country wants to build and produce indigenous fighters under the KF-X initiative.
The  KF-X program aimed at developing a Korean made F-16 type fighter has  also been under heated debate over its economic and technical  feasibility.
For  the F-X III competition, the F-35 Lightening II being developed by  Lockheed Martin of the U.S. has often been referred to as a frontrunner  because of the ``fifth-generation'' fighter's inherent stealth  technology that helps it evade enemy radar detection.
But  recent reports over a series of cost overruns and delays related to the  F-35 development program have apparently disappointed South Korean  procurement officials, dimming its prospects in the F-X III contest.
``There  is a lot of uncertainty as to the F-X III and KF-X plans, so I can't  even provide the prospects of the fighter acquisition programs,'' a  researcher on air force improvement programs at the state-funded Korea  Institute Defense Analyses (KIDA) told The Korea Times. ``As for the F-X  III, truth be told, the fate of the F-35 program is a key factor in  increasing uncertainty.''
F-35 Problems

Earlier  this month, the U.S. Air Force announced a two-year delay in the  production of the F-35 stealth fighter, also known as the Joint Strike  Fighter (JSF).
The  aircraft had been scheduled for use by 2013, but the U.S. Air Force  said the aircraft would not be ready until the end of 2015.
Lockheed  Martin had been confident that its F-35 would get the upper hand in the  third phase of the F-X competition and said South Korea would be able  to procure aircraft as early as 2014.
In  February, U.S. Defense Secretary Robert Gates sacked a key official in  charge of the F-35 program over the projected delay and cost overruns.
The  Pentagon believes the cost of the F-35 will be more than double the  original price. According to the Pentagon's chief weapons buyers, the  cost of the aircraft would go from $50 million a jet in 2001 to about  $113 million.
Lockheed officials told Korean authorities earlier that the cost for the F-35 would be between $50 million and $63 million each.
The  KIDA researcher said he believes South Korea's purchase of F-35  aircraft would be scrapped or delayed for several years later than  scheduled. He earlier indicated that adopting an early version of the  F-35 could cause operational risks.
The  F-35 development program has been underway with nine international  contractors and government partnerships, including Britain, Italy, the  Netherlands and Turkey since 2001. The JSF has three different versions ―  A-type for air force operations, B-type for short takeoff and vertical  landing for naval and marine missions and C-type for operations with  aircraft carriers.
The F-35 is a single-seat, single-engine fighter that can perform close air support, tactical bombing and air defense missions.
More F-15Ks

Boeing  is expected to capitalize on the emerging problems with the F-35 when  it touts its F-15 Eagle aircraft to the South Korean Air Force.
But  the winner of the first and second phase F-X competitions will also  face an uphill battle this time to persuade South Korea to buy more of  the aircraft, which some critics call a good but older platform.
``Needless  to say, the F-15K is one of the best fighter jets in the world,'' an  Air Force official said. ``But there is doubt as to whether a fleet of  only F-15Ks would be efficient, or if a combination of long-range and  stealth aircraft would be better. The Air Force, KIDA, the Defense  Acquisition Program Administration and other parties concerned will  study this issue more during the year.
''In  a move to attract South Korea's fresh attention, Boeing unveiled a new  version of the F-15 aircraft, the Silent Eagle, which the aerospace firm  says has a ``semi-stealth'' function while retaining the F-15's  traditional long-range, large payload capability.
Boeing  completed radar-cross-section (RCS) trials for the Silent Eagle  prototype last August and September and is looking to its first flight  in coming months.
Industry  sources, however, say it remains to be seen whether or not the U.S.  government will approve the sale of radar stealth technology for the new  jet, or how much higher levels of RCS Boeing will offer to meet South  Korean requirements.
Joe  Song, vice president of Asia-Pacific international business development  with Boeing Defense, Space and Security, said during last year's Seoul  Air Show that his company would offer a key option to transfer advanced  fighter development technologies to South Korea for a homegrown fighter  under the KF-X project.
``We're  considering connecting the third phase F-X deal to the KF-X program if  necessary, given that packaging some related programs, in general,  creates a synergy effect,'' he said.
In  the KF-X program, South Korea aims to develop and produce between 120  and 250 F-16 type fighters beginning in 2013, with technology support  from foreign aerospace companies.
If  Silent Eagle's marketing proves to be unsuccessful, Boeing could offer  the F-15K variant with improved avionics and radar systems, sources  said.
The  twin-engine F-15K is capable of air-to-ground, air-to-air and air-to-sea  missions day or night, under any weather conditions. It has a  23,000-pound payload and can fly at a maximum speed of Mach 2.3, with a  combat radius of 1,800 kilometers. A single aircraft costs around $100  million.
European Option
 
  The  European consortium Eurofighter wants to look for an opportunity in  South Korea but is still suffering the trauma of a defeat in the F-X I  competition in the early 2000s.
European  industry officials believe the Rafale built by French aircraft firm  Dassault initially received more favorable reviews from the Korean  military than Boeing's F-15K, but the Korean government selected the  U.S. fighter jet allegedly due to a political consideration.
Eurofighter  wants South Korea to join its Eurofighter Typhoon program and says it  could offer more lenient technology transfer for the KF-X program.
``Eurofighter  apparently has a chance to compete for the F-X III given the two main  U.S. competitors are not in a good position now. But the European firm  has not been so active in promoting its fighter,'' an official at the  Defense Acquisition Program Administration said. ``It's up to the  European firm and what the company will offer in the competition.
''The  Eurofighter Typhoon is Europe's biggest-ever military aviation program  with about 700 aircraft under contract with five European nations and  Saudi Arabia.
The  Typhoon is a twin-engine canard-delta wing multirole fighter. Powered  by two Eurojet afterburning turbofans, the stealth aircraft has a  maximum speed of Mach 2.0 and can supercruise at up to Mach 1.5 without  using afterburners.
The  fighter has a maximum range of 3,790 kilometers and can carry a typical  payload of two laser-guided bombs, four beyond visual-range air-to-air  missiles, four short-range air-to-air missiles and two standoff-range  weapons.
