The Norwegian Advanced Surface-to-Air Missile Systems (NASAMS) Taiwan ordered from the US would be installed in strategically important positions in Taipei and New Taipei City to guard the region, the Ministry of National Defense said in statement, Report informs via Taipei Times.

The air defense system would be deployed in Taipei’s Songshan District and New Taipei City’s Tamsui District, the ministry said, adding that the systems could be delivered as soon as the end of this year.

The US Defense Security Cooperation Agency has previously said that three NASAMS would be sold to Taiwan.

The weapons are part of the 17th US arms sale to Taiwan during the administration of US President Joe Biden.

The system is designed for the ground-launched version of the US-made AIM-120 Advanced Medium-Range Air-to-Air Missiles (AMRAAM) and AIM-9X Sidewinder missiles, as well as Europe’s jointly developed IRIS-T SLS short-range missiles.

NASAMS are compatible with the AN/MPQ-64 Sentinel radar system and use Link-16 tactical data link technology.

The AMRAAM-ER, the extended-range variant of the AIM-120, is capable of intercepting aircraft and supersonic cruise missiles. It has a range of about 50km.

NASAMS would give medium-altitude capability to supplement Taiwan’s other air defense systems, including the land-based variant of the Tien Chien II (Sky Sword II) and Tien Kung (Sky Bow) families of missiles, as well as the Patriot Advanced Capability-3 (PAC-3).

The Tien Chien II is a mobile air defense system designed to protect ground forces with a range of 15km, while the Tien Kung family have a maximum interception altitude of 45km. The PAC-3 has a maximum interception altitude of 24km.

The ministry also announced two other weapons procurements contracts — one for L-band electronic radar arrays and another for non-L-band electronic radar arrays, as well as four logistics and sustainment contracts for several systems.

The radar contracts are likely to be for AN/TPS-77 and AN/TPS-78 forward warning systems.

The NASAMS and radar array contracts have a listed allocation of NT$24.3 billion ($737.17 million) and are to be implemented by February 2034 and March 2030 respectively.

The air force’s 793rd Air Defense Brigade would receive spare parts for air defense missiles and support for PAC-3 systems in two contracts allocated a combined NT$2.33 billion.
