The Tank Boat Antasena-class is a new patrol boat jointly developed and designed by the Belgian company John Cockerill Defense in collaboration with the Indonesian Defense Industry PT Pintad and PT Lundin. The new patrol boat is based on a catamaran design that provides a stable weapons platform for close-in and long-range fire support in normally inaccessible coastal and riverine environments. She integrated the John Cockerill Lundin first announced the tank boat concept in 2014. The tank boat was first unveiled in Indo Defence 2016 in the form of a full-size mockup. The mockup was equipped with Cockerill 3105 turret. In 2018, the Ministry of Defense ordered one X18 tank boat to add to the TNI AD facilities as well as evaluate the boat's performance. The first prototype had begun sea trials on April 28, 2021. Then on May 22, 2021, she was ordered by the Ministry of Defense to undergo a sea trial from the dock in Banyuwangi to the waters of Paiton, Probolinggo. After arriving at the Indonesian Navy's firing range in Paiton, the tank boat underwent a firing test using its main weapon, the 30 mm cannon. Apart from Indonesia, the Tank Boat has garnered some interest from India, Greece, the Philippines, and the United Arab Emirates.

Antasena-class combat boat variants:

The X-18 Tank Boat can be fitted with 25/30 mm, 30/40 mm, or 105 mm cannons from John Cockerill Defense.

Technical Data

The Tank Boat Antasena-class X18 uses a two-hull design with a composite material that is claimed to be ten times stronger than steel, but ten times lighter than the same material. X 18 ATC is manufactured using the best available technology — Full Carbon Fibre, Vacuum Infused Composites Utilizing Vinylester Resin with Sand-wich Corecell and Multiaxial Carbon Fibre. The main cabin, wheelhouse, doors, and windows are ballistic protected using Composites Polyethylene Panels rated to NIJ Level Ill – IV protection. It has a length overall of 18.00m, a beam of 6.10m, and a draught of 0.90m.
The X18 tank boat uses the main engine in the form of two MTU V12 2000M86 diesel engines with a power of 1700 horsepower. The X18 is also equipped with the MJP 550 Waterjet propulsor. With a fuel tank capacity of around 6000 liters, the X18 is able to reach destinations as far as 600 nautical miles (1,100 km) without refueling.
The main weapon system of the X18 Tank Boat is the John Cockerill Defense Cockerill 3105 turret. This system is based on a versatile and powerful high-pressure low recoil-force Cockerill 105mm gun. Fully stabilised, accurate by day or night, and able to use a wide range of NATO standard 105mm ammunition, this weapon system directly engages a broad spectrum of targets at up to 5,000m range, and indirectly engages targets to 10,000m range. The powerful, accurate and flexible Cockerill C3105 weapon system gives the X18 Tank Boat Commander a wide range of tactical options at all stages of his mission. The 105mm is also capable of firing the Cockerill Falarick 105 Gun Launched Anti-Tank Guided Missile (GLATGM). Elevating to +42° the weapon delivers exceptional engagement capability in complex situations, and the GLATGM permits hard and Point targets to be engaged at extended ranges (up to 5 km). The mounting of this type of system allows for flexibility in logistics with the various calibers already in common use with NATO and other major military powers. This is the first time that any company has conceived of mounting this type of system aboard a small, fast and stealthy catamaran that with only a 1-meter draught makes it ideally suited for the confines of coastal waterway operations.
Sensors, Electronics and Decoys
The Tank Boat is fitted with Doppler Radar with CHIRP Pulse Compression, four Multi-mission Monitors, an Integrated Navigation Computer, GPS/AIS, and Transducer Multisensor with Depth, Speed, and Temperature Functions.
Giving it the ability to execute beach and landings and insert or extract river squads of up to 60 Special Forces or Marines. The X 18 ATC has a crew of 5, and the aft deck working area is rated up to 5 tons for carrying logistic cargo, troops, drones and a high-speed Interdiction inflatable Raiding craft for boarding and Seal insertion.
