The second batch of 21 F-15Ks was approved in April 2008 at a budget of 2,3 trillion won (2,3 billion US-Dollars).
The South Korean fighter programme for 40 F-15Ks was valued at a total of around 4,25 billion US Dollars as of 2005. The Boeing part of the deal is around 3,6 billion Dollars while General Electric has said its 88 engines cost 340 million Dollars. Also, training and weapons are contracted through FMS for 300 million Dollars.
After the F-15K was selected, the South Korean defence ministry achieved a price cut from 4,467 billion Dollars to 4,228 billion Dollars (- 239 million, including 36 million in contract adjustments)
Republic of Korea Air Force: 40, to be delivered between October 2005 and August 2008. Another 20 will probably be ordered in 2008 for deliveries starting in 2010.
In South Korea, the F-15K competed with:
The F-15K is an F-15E with specific equipment improvements for the Republic of Korea Air Force (ROKAF). Systems fit of the most modern Eagle variant includes:
- Raytheon AN/APG-63(V)1 radar with added capabilities for ground-moving target track, sea surface search/track and enhanced high-resolution ground mapping. Also, a ten-fold improvement in reliability is claimed over the APG-70 in the F-15E
- Third-generation targeting and navigation FLIR (Tiger Eyes from Lockheed Martin), with IRST in the pylon
- Enhanced tactical electronic warfare suite including BAE Systems ALR-56C(V)1 warning receiver and Northrop Grumman ALQ-135M jammer (contract worth 160 million Dollars) as well as BAE Systems AN/ALE-47 countermeasures dispenser
- new cockpit displays from Kaiser (seven AMLCDs, three are 12,8 x 12,8 cm, four are 15,2 x 15,2 cm) plus 10,2 x 10,2 cm active matrix flat-panel up-front control panel from L-3 Communications as well as Joint Helmet Mounted Cueing System
- Honeywell Advanced Core Processor, ten times better than older F-15 central computer
- IFF system (AN/APX-113 Combined Interrogator Transponder) from BAE Systems
The deal with South Korea also includes a F-15K Weapon System Trainer and a Cockpit Procedure Trainer, also supplied by Boeing.
Offset agreements were in the contract, and Boeing stated that it was committed to helping address Korea´s industrial and technology development priorities, including the stated desire to produce an own fighter by 2015.
In the second half of the 1990s, South Korea conducted some studies on a new fighter to complement its F-16s.
In 1999, South Korea had earmarked 3,2 billion US-Dollars for the F-X fighter programme, intended to replace its remaining 50 F-4 Phantom IIs.
First bids for the F-X were handed over by Boeing, Dassault, Eurofighter and Sukhoi in June 2000.
ROKAF pilots conducted a flight evaluation of the F-15E Strike Eagle in October 2000 at Elmendorf AFB in Alaska. Boeing leased three aircraft for the 14 flights.
During 2001, the date for a decision in the F-X programme slipped progressively from July to September and then into 2002.
Priced offers were expected on 14 January 2002. Apparently, all were too high so that a second deadline of 24 January was given to lower the price.
On 27 March 2002, the South Korean defence ministry eliminated the bids from Eurofighter and Sukhoi. This started a second phase evaluation, mainly based on foreign policy, security alliance, economical and industrial aspects.
On 19 April 2002, the South Korean Ministry of National Defense (MND) announced that it has completed the F-X evaluation and chosen the F-15K. „We settled on Boeing´s F-15K after taking into account security, diplomatic and trade partnerships with bidder´s countries in the final round of competition“, said Brig. Gen. Hwang Euidong, spokesman for the MND.
Boeing agreed to a price cut of 239 million US-Dollars in mid-May 2002, clearing the way for contract signature later in the year. Thus, the price came down to what Dassault had offered for its Rafale.
Design work for the F-15K airframe was completed in April 2003, when Boeing began assembly of the central fuselage section. The critical design review for the systems development activities followed at the end of 2003.
Final assembly of the first F-15K for South Korea started in May 2004 at St. Louis. It was completed in October.
Samsung Techwin Co. delivered the first F110 assembled in South Korea on 10 December 2004.
Flown by Boeing Chief F-15 test pilot Joe Felock and Chief Weapons System Officer Rick Junkin, the F-15K made its first flight on schedule on 3 March 2005. It reached over Mach 2 and accomplished engine shutdowns and restarts.
The first F-15K was presented on March 16, 2005, at St. Louis. The ceremony was attended by General Lee, Han-ho, the ROKAF Chief of Staff.
Boeing accepted the first F-15K fighter jet wing and forward fuselage made by Korea Aerospace Industries (KAI) at a ceremony April 18 in Sachon, South Korea. Boeing selected KAI to produce aircraft components for 32 of the 40 Republic of Korea Air Force F-15Ks. Once completed, the wings and forward fuselages are sent to St. Louis where the new fighters complete final assembly.
On 4 August 2005, Boeing said that the first Standoff Land Attack Missile-Expanded Response (SLAM-ER) for the Republic of Korea Air Force (ROKAF) had been rolled out recently during a ceremony at Boeing's Weapons Enterprise Capability Center in St. Charles, Mo. The Republic of Korea is the SLAM-ER's first international customer.
Deliveries of F-15Ks to the ROKAF will run from October 2005 (aircraft K3 and K4, to be presented at the Seoul Air show) to August 2008. At the time of selection in 2002, deliveries were planned as 2 in 2005, 10 in 2006, 16 in 2007 and 12 in 2008.
After 15 months of training, four South Korean pilots and four weapons systems officers graduated September 9, 2005 from training in St. Louis, where they learned the differences between the F-15E Strike Eagle and the F-15K. The training had started in June 2004 with six months of language classes at Lackland Air Force Base, Texas. From there, the aircrew was introduced to the F-15E to begin eight months of transition and instructor training at Seymour Johnson Air Force Base, N.C., before heading to St. Louis for the final three weeks of training.
Two F-15K Strike Fighters made an appearance at Seongnam Air Force Base south of Seoul on Friday (7 October 2005) after a flight time of 20 hours covering 15,962 kilometers from Boeing's St. Louis plant in Missouri. En route to Korea from the St. Louis plant, the planes touched down at Hickam Air Force Base, Hawaii, and then at Guam Anderson Base before heading for Seongnam Base.
On 12 December 2005, a ceremony marking the introduction of the F-15K to South Korea took place at the 11th Fighter Wing Squadron of the Air Force at Daegu, with the attendance of ranking officials, including Defense Minister Yoon Kwang-ung and Air Force Chief of Staff Gen. Kim Sung-il. It was said that the multi-role aircraft will be deployed in the field for operational flights starting in January 2007.
In February 2006, the first guided release of JDAMs from an F-15K were completed at Eglin Air Force Base, Florida. Three JDAMs (Mk 82 bomb cases) were dropped simultaneously and all hit their targets.
The F-15K became the first Eagle variant to release a SLAM-ER standoff weapon on 27 March 2006. The firing was made at Point Mugu, California, at 25000 ft and Mach 0.8, around 180 km (100 NM) from the target.
On 18 May 2006, the South Korean defence ministry approved a plan to buy another 20 F-15Ks at around 2 billion US-Dollars, with deliveries beginning in 2009. A final endorsement of the plan by president Roh Moo-huyn was needed, it was said at the time.
In early 2007, South Korea decided to hold a competition for the second tranche of the F-X programme, apparently to diffuse criticism that it favoured US weapons. Potential bidders like Boeing, Dassault, Eurofighter, Lockheed Martin and Sukhoi were invited to attend briefings and an RFP was issued. At the deadline of 18 April 2007, only Boeing had responded. The other companies apparently did not find it worthwhile to expend efforts on a lost cause.
The South Korean defence procurement agency then issued another public notice on 23 April, with a deadline of 10 May 2007. Again, Boeing was the only respondent. It thus seemed that contract negotiations could start. A formal order signature was expected around February 2008 and deliveries starting in 2010. The programme was estimated at 2,4 billion US-Dollars.
On 25 April 2008, the “defense project promotion committee” confirmed selection of the F-15K for the second batch of the F-X programme. For a budget of 2,3 trillion won (2,3 billion US-Dollars), 21 aircraft will be acquired between 2010 and 2012, it was said. The new aircraft will be fitted with Pratt & Whitney F100-PW-229 turbofans instead of GE F110s, it was announced.
