The Japan Maritime Self-Defense Force (JMSDF) launched the first two Sakura-class offshore patrol vessels (OPV) at the Japan Marine United shipyard on 13 November. This marked a key step in the Ministry of Defense’s efforts to strengthen protection of the country’s territorial waters.
Named after botanicals, the lead vessel is Sakura (pennant number ‘901’) followed by Tachibana (‘902’). They are the first of a planned dozen OPVs destined for the JMSDF.
The OPV design incorporates a large helicopter deck and a crane mounted above the hangar for handling modular mission systems. A distinctive curved sheer line may help reduce the radar signature of the vessel’s prominent superstructure.
According to the Acquisition, Technology and Logistics Agency (ATLA), the class displaces around 1,920 tonnes and measures 95m in length. The vessels use a combined diesel-electric and diesel (CODLAD) propulsion arrangement, which gives a maximum speed of roughly 20kt.
Armament is limited to a single 30mm cannon, reflecting the OPV’s constabulary role, although reports indicate the vessels will operate the Shield AI V-BAT vertical take-off unmanned aerial vehicle to bolster maritime domain awareness.
For the next fiscal year, Japan’s Ministry of Defense has requested JPY28.7 billion (US$183.7 million) for OPV construction, likely covering payments for the fifth and sixth hulls. The third and fourth vessels are scheduled to be launched in 2026.
Beyond surface combatants, Japan is also upgrading its ship-to-shore capabilities in preparation for possible island contingencies.
On 6 November, for instance, the third Nihonbare-class landing craft utility, christened Aozora, was launched. This landing craft will join the newly established Joint Maritime Transport Group.
