JS Kaga (DDH-184) is a helicopter carrier with a planned future conversion into an aircraft carrier. Officially classified as a multi-purpose operation destroyer, she is the second ship in the Izumo class of the Japan Maritime Self-Defense Force (JMSDF).
The JS Kaga can carry up to 28 aircraft, or 14 larger aircraft. However, only 7 anti-submarine warfare helicopters and 2 search and rescue helicopters are planned for the initial aircraft complement. For other operations, 400 troops and 50 3.5-ton trucks (or equivalent equipment) can also be carried. The flight deck has five helicopter landing spots that allow simultaneous landings or take-offs.
The JS Kaga is armed with two Phalanx CIWS (Close-In Weapon Systems) and two SeaRAM CIWS.
The Murasame-class is a class of destroyers, in service with the Japan Maritime Self-Defense Force (JMSDF). This is the first class of the second-generation general-purpose destroyers of the JMSDF. The Murasame Class destroyer is armed with an Mk48 VLS (vertical launching system) firing Sea Sparrow and Evolved Sea Sparrow surface-to-air missiles. The Mk41 VLS installed below the deck can fire RUM-139 VL ASROC (anti-submarine rockets). The ship is also armed with one OTO Melara 76 mm naval gun, two 20 mm Phalanx CIWS (Close-In Weapon Systems) and two triple 324mm torpedo tubes.
The Murasame class is powered by a combined gas turbine and gas turbine (COGAG) propulsion system. Two General Electric LM2500 boost gas turbines and two Rolls-Royce Sprey SM1C cruise gas turbines deliver a total power output of 60,000ps. The propulsion system provides a maximum speed of 30 kts and a range of 8,350 km at a cruising speed of 18 kts.

The Indonesian Navy KRI Sutanto (377) Parchim-class corvette and the KRI John Lie (358) Bung Tomo class corvette were involved during the maritime exercise. Currently, 14 of 16 Parchi-class corvettes are in service with the Indonesian navy. The 16 Parchims from the GDR were purchased by Indonesia in 1992 in a deal worth US$12.7 million arranged by then Minister of Research and Technology, Dr B.J. Habibie. The transfer from the Volksmarine also included 14 Frosch-class landing ships and 9 Kondor-class minesweepers.
Indonesian Parchims has completed a major refit to fulfill Indonesian navy needs. The one twin 57 mm gun AK-725 and one twin 30 mm gun AK-230 were retained except for the ship 376 where the 30mm AK-230 replaced by Chinese made Type 730 CIWS. The RBU-6000 also retained as a major armament. Two SA-N-5 SAM removed and replaced by two Vektor G12 20mm guns. Four 400mm Russian made torpedo launcher was out of service because there is no Russian made torpedo in Indonesian navy inventory so this Russian made torpedo launcher replaced by two western made triple torpedo launcher but only for two ships.
The Bung Tomo class is a class of three Indonesian multi-role patrol corvettes. They were originally built for the Royal Brunei Navy and named Nakhoda Ragam-class corvettes but were ultimately bought by Indonesia and renamed.
The armament of the Bung Tomo class consists of a 76SR "Super Rapid" 76 mm/L62 dual-purpose gun, and two DS30M 30 mm anti-aircraft guns. The missile battery includes of 16 vertical launch cells for the Seawolf SAM, and 8 container/launchers for the MM.40 Exocet anti-ship missiles. Two STWS triple-tube launchers for 324 mm torpedoes are mounted amidships; though these are British-made torpedo tubes, they are used to launch US-made Mk.46 torpedoes.
