The US State Department has approved a possible foreign military sale (FMS) of two MK 15 MOD 25 Phalanx Close-In Weapons System (CIWS) Block 1B Baseline 2 (IB2) systems to South Korea.

The sale has a total estimated value of $39m and includes associated equipment.

Under the deal, South Korea has also requested the sale of 4,000 rounds, 20mm cartridge API linked, spare parts, ammunition, software, training, and engineering technical assistance.

Other related elements of the programme and logistical support are also included under the deal.

Raytheon Missiles and Defense has been appointed as the principal contractor for the sale.

The US Defense Security Cooperation Agency (DSCA) has notified Congress about the sale.

DSCA said in a statement: “The proposed sale will improve the Republic of Korea’s capability to meet current and future threats.

“Korea will use the systems aboard its first KDX III Batch II Class ship to provide it with effective means of detecting and defending itself against incoming airborne threats.”

In a separate development, the department also approved a potential FMS of MK 54 lightweight torpedoes and related equipment to Brazil for $70m.

Brazil has requested the sale of 22 MK 54 conversion kits to convert MK 46 Mod 5 A(S) torpedoes to MK 54 Mod 0 lightweight torpedoes.

According to DSCA, Brazil plans to use MK 54 lightweight torpedoes on its Sikorsky S-70B ‘Seahawk’ aircraft and surface ships.

Raytheon Integrated Defense System in Portsmouth will act as the principal contractor for this sale.

Earlier this month, Canada requested the sale of  Standard Missile 2 (SM-2) Block IIIC missiles from the US.
