Lockheed Martin has delivered a AN/SPY-7(V)1 radar system comprising four radar antennas for the Japan Maritime Self-Defense Force’s (JMSDF’s) first Aegis System Equipped Vessel (ASEV) scheduled to be commissioned in fiscal year (FY) 2027.
The radar system was delivered to the Japan Ministry of Defense (MoD) through Mitsubishi Corporation under a Direct Commercial Sale arrangement, Lockheed Martin announced on 7 July.
Chandra Marshall, vice-president of multidomain combat solutions at Lockheed Martin said, “We will continue full system integration and testing with all four antennas at the Production Test Center in Moorestown, New Jersey, this year, prior to equipment delivery to Japan, which will significantly reduce integration risk and enable commissioning on schedule.”
In January Lockheed Martin announced it had delivered the first antenna for this radar system to the MoD.
AN/SPY-7(V)1 is based on Lockheed Martin’s Long Range Discrimination Radar (LRDR), which is a 3D S-band gallium nitride (GaN)-based radar with an estimated range of 4,828 km for terrestrial objects and an estimated range of 46,000 km for space-based targets.
Japan is procuring two AN/SPY-7(V)1 radar systems from Lockheed Martin for the JMSDF’s two ASEVs. The first ASEV is being built by Mitsubishi Heavy Industries (MHI) while the second ASEV – scheduled to be commissioned in FY 2028 – is being built by Japan Marine United Corporation, under contracts secured by the two companies from the MoD in September 2024.
