Typhoon armed with 25 mm gun on Shaldag class fast patrol boat of the Israeli Navy.

The Typhoon is a type of remote weapon station manufactured by Rafael Advanced Defense Systems of Israel, and it shares similar design principles and common technologies with Samson Remote Controlled Weapon Station (Samson RCWS), a land-based system manufactured by the same developer. Like Samson RCWS, Typhoon is also multi-configurable.

The Typhoon, and its lightweight variant, Mini Typhoon, are used by the Israeli Navy, Royal Australian Navy, Royal New Zealand Navy, the Republic of Singapore Navy[1] and Singapore's Police Coast Guard.[2]


The first Typhoon, the Mk-23, was released in 1997. The weapon is mounted on a stabilized deck mounting which allows it to remain on target as the platform beneath it moves. The stabilizer has an accuracy of 0.25 mrad, allowing it to keep the weapon aimed to within 250 millimetres (9.8 in) on a target 1,000 metres (3,300 ft) away.

The mounting does not penetrate the platform, making it relatively simple to fit the weapon to ships. Typhoon can use sights attached to the weapon mount or it can receive inputs from an independent Electro-Optical Detector (EOD) or Fire Control Radar (FCR). Using its own sight the Typhoon system can provide firing solutions entirely without outside assistance, allowing it to function fully independently.

The cannon system mounted can be an ATK, Oerlikon, Mauser or Giat model in the 20–30 mm caliber range. Between 160 and 210 rounds are carried on the mounting, depending on the caliber. The mount can traverse 120° to either side and elevate between -12.5° and 40.5°. The weight of a complete system is between 690 and 750 kilograms (1,520 and 1,650 lb) without ammunition, depending on the guns and sensors mounted.

By 2006, more than 120 Typhoon systems had been ordered.[citation needed]


Mini Typhoon

Mini Typhoon is a lightweight, remote-controlled weapon station based on the Typhoon.[3] It can be fitted with a .50 caliber machine gun, a 7.62 mm machine gun or a 40 mm grenade launcher, with a magazine of up to 230 rounds.[3] The system has an accuracy rating of 0.5 mrad, weighs between 140 and 170 kilograms (310 and 370 lb), depending on the weapon fitted, and can be installed without structural penetration of a ship's deck.[3] The mini Typhoon is also mounted on the Protector USV Mk49 Mod0.[4]

  • Typhoon Weapon System has been selected by the US Navy, designated Mk38 Mod2, and provided by the US-located branch of the UK-headquartered company BAE Systems teamed with Rafael.[5]
  • Mini-Typhoon selected by the US Navy as the Remote Operated Small Arms Mount (ROSAM), designated Mk 49 Mod 1. The combination Spike missile/12.7mm armed variant has been tested on an unmanned vessel.[6]
