The Defense Security Cooperation Agency (DSCA) said Wednesday it notified Congress March 29 of potential Foreign Military Sales (FMS) to South Korea potentially worth a combined $13.2 billion for 60 conventional F-35s and support for 60 F-15s.

The F-35 sale, worth potentially $10.8 billion, would also include nine Pratt & Whitney F135 engines as spares; electronic warfare systems; command, control, communication, computer and intelligence/communication, and navigation  (C4I/CNI); Autonomic Logistics Global Support System (ALGS); Autonomic Logistics Information System (ALIS); full mission trainer; weapons employment capability and other support. Pratt & Whitney is a division of United Technologies Corp. [UTX]

The F-15 support sale procured via Direct Commercial Sales (DCS), worth potentially $2.4 billion, would include 60 Active Electronically Scanned Array (AESA) radar sets, 60 Digital Electronic Warfare Systems (DEWS), 60 AN/AAQ-33 Sniper Targeting Systems, 60 AN/AAS-42 Infrared Search and Track (IRST) systems, 132 Ultra High Frequency/Very High Frequency (UHF/VHF) secure radio with Have Quick II, 69 Link-16 terminals and spares, the Advanced Display Core Processor II, Joint Mission Planning System, one Gem-V Global Positioning System (GPS) airborne receiver module and various parts and equipment.

South Korea is conducting a competition among the F-35, F-15 and Eurofighter Typhoon. Boeing [BA] produces the F-15, Lockheed Martin [LMT] makes the F-35 while European Aeronautic Defense and Space (EADS); Alenia Aermacchi, a division of Finmecannica; and BAE Systems builds the Eurofighter Typhoon.

The deal is contingent on Congress’ approval.
