The State Department on June 29 said it has approved and notified Congress of a potential $1.3 billion arms sale to Taiwan that includes support and upgrades for a Lockheed Martin [LMT] surveillance radar program and Raytheon [RTN] air-to-surface weapons, torpedoes, and other systems.

The proposed foreign military sales include $400 million related to technical support for early warning radar surveillance and $80 million for upgrade of the Raytheon AN/SLQ-32A electronic warfare shipboard suite.

The potential deal also includes a $250 million sale for 46 of the Raytheon Mk-48 6AT heavy weight torpedoes, a $175 million upgrade of the Mk-46 torpedo to the Mk-54 torpedo, $185.5 million for 56 air-launched AGM-154C Joint Stand-off Weapons, $147.5 million for 50 AGM-88 High-Speed Anti-Radiation Missiles, and $125 million SM-2 fleet-area air defense missile components.

The SM-2 sale includes 16 Block IIIA all-up rounds, 47 MC 93 MOD 1 Block IIIA guidance sections, and five target detecting devices.

The Pentagon disclosed the proposed sales. It didn’t list a contractor for the work on the surveillance radar program.

Congress must still approve the sales.
