The Defense Security Cooperation Agency said Tuesday it notified Congress of a possible Foreign Military Sale to Australia of 12 EA-18G modification kits to convert Boeing’s [BA] F/A-18F Super Hornet fighter jets to the G configuration.

In addition to associated parts, equipment, training and logistical support, the deal has an estimated price tag of $1.7 billion, according to a DSCA statement.

Also included in the deal would be 34 AN/ALQ-99F(V) tactical jamming system pods, 22 CN-1717/A Interference Cancellation Systems (INCANS), 22 R-2674(C)/A Joint Tactical Terminal Receiver (JTTR) systems, 30 LAU-118 guided missile launchers, Command Launch Computer (CLC) for High Speed Anti-Radiation Missile (HARM) and Advanced Anti-Radiation Guided Missile (AARGM), as well as spares, support, test equipment and documentation, according to a statement.

Congress would have to sign off on the deal for it to go through.
