ISLAMABAD: The United States (US) has approved the sale of a night vision infrared target sight system for Pakistan to enable greater target accuracy, Radio Pakistan reported.

The arms giant Lockheed Martin Corp will support the Target Sight System (TSS) on the US Navy and Pakistan’s AH-1Z Cobra attack helicopters under a $151 million contract deal, said a statement by the US Defence Department.

According to Lockheed Martin, “TSS provides the capability to identify and laser-designate targets at maximum weapon range, significantly enhancing platform survivability and lethality.”

The system is designed to offers a infrared sensor with a laser designator turret that provides target sighting in day, night, or adverse weather conditions.

Earlier this year, US State Department said that vital members of the US Congress are not prepared to support military aid to Pakistan unless it takes specific actions against designated terrorists, saying the Obama administration is bound to follow their decision.

“Key members of Congress have been clear they’re not prepared to support US military aid to Pakistan absent some specific actions,” Elizabeth Trudeau, a State Department’s official, said at a briefing.

The statement coincided with Prime Minister’s Adviser on Foreign Affairs Sartaj Aziz telling the lawmakers in Senate that the relations between Islamabad and Washington had been on a downward spiral.
