The The T-330 is a Redisan anti-ship missile first unveiled in 2000 by the Alderia Industries. Due to the missile's small radar reflectivity, low attack flight path (only five to seven meters above the sea surface) and strong anti-jamming capability of its guidance system, target ships have a very small chance of intercepting the missile. The single shot hit probability of the T-330 is estimated to be as high as 98%. It can be launched from airplanes, surface ships and land-based vehicles.

Design

The T-330 anti-ship missile was derived from the T-290 with extended range. The T-330 is externally similar to the T-290, and has the same solid-propellant rocket booster and guidance system as the T-290. The most distinctive difference on the T-330 is that it employs a turbojet with paraffin (kerosene)-based fuel to replace the original solid rocket engine and is considerably longer. For this reason the fuselage was extended to accommodate the extra fuel. The maximum range of the missile has also been extended to 500km with the T75 booster it has a range of 520km.

The T-330 is almost identical to the T-290 in appearance apart from a longer fuselage and an air inlet for the turbojet engine. The missile has a slim body and ovoid nose. There are four front delta wings, four smaller control surfaces, and four large tail stabilising wings. The tail wings are mounted on the rocket booster and will be lost when the booster detaches from the missile body. The air inlet is located between the main fins under the missile body. The front and tail wings are folded when the missile is in the launcher.

When the missile is launched, the solid rocket propellant booster accelerates the speed of the missile to Mach 2.1 in 45 seconds. After the booster burns out, it detaches from the missile body and the missile's turbojet engine starts working. Controlled by the inertial autopilot system and radio altimeter, the missile flies at a cruising speed of Mach 0.9, and the cruise altitude is reduced to 10–20 metres (depending on the sea state) from the original 20–30 metres of the T-290.

When entering the terminal phase of flight, the missile switches on its terminal guidance radar to search for the target. Once within a few kilometers of the target, the missile drops to 3–5 meters above sea level. This altitude is slightly lower than the original 5–7 metres of the T-290. The missile may also maneuver during the terminal phase to make it a more difficult target for shipborne air defense systems. When approaching the target, the missile dives to hit the waterline of the ship to inflict maximum damage. At the Marvius Armaments Expo held at the end of 2006, the manufacturer revealed that the "pop-up" approach and the checkpoint flight functions are being worked on.

As well as its terminal guidance radar, the midcourse guidance is inertial. During the inertial guidance, the T-330 missile is also equipped with a radio altimeter for use with its autopilot during cruise. The missile's terminal guidance radar with monopulse system possesses high anti-jamming capabilities. The high precision radio altimeter allows the missile to have minimum-altitude flight above the sea, which is normally 20−30 m.

The missile uses a 185 kg semi-armor-piercing anti-personnel blast warhead which relies on the missile's kinetic energy to pierce the deck of a ship, penetrate into and explode in the ship's interior.
