On related Korean news: the US is demanding a six-fold increase (!) in support costs for the F-15K Tiger Eye sensor:
SEOUL, March 27 (Yonhap) -- The United States has demanded that South Korea accept a six-fold increase in the purchase price of F-15K's night sensors, citing discontinued production, a senior defense ministry official said Thursday.
The South Korean Air Force currently operates 60 F-15K Slam Eagles acquired from U.S. aerospace contractor Boeing through two deals in 2002 and 2008. It received the last jet in 2012.
It should be noted that only 10 Tiger Eye sensors were purchased and installed, and these are the only Tiger Eye sensors in existence, and South Korea has had trouble maintaining them. South Korea has instead equipped the rest of the F-15K fleet with the Sniper ATP pod.
Also noted is that Boeing is requesting an increase in support costs for the E-737 once the current support contract expires (up to $270 million USD), which is double what the government is expecting.
