According to MBDA, the new configuration extends the weapon's over-the-horizon capability from 70 km to a maximum range of 180 km, utilizing on-board GPS, and the introduction of land-attack mode, enabling operators to set target coordinates in longitude, latitude and elevation. This new capability significantly enhances the missile's anti-ship capability, as the new Block 3 can approach the target through a preplanned 3D flight trajectory, performing the terminal attacks from the least predictable direction, at very low sea skimming altitude. For the terminal phase guidance, the missile utilizes a J-band active radar seeker with adaptive search patterns which selectively discriminates between targets at sea and GPS designated coastal based targets.
The missile are complemented by a new version of the mission planning system, enabling operators to maximize the use of the new features exploiting the missile's capability to penetrate the target's defenses.
The Block 3 airframe design is optimized with low signature characteristics. Its extended range is derived by a new propulsion system that includes a booster and turbojet sustainer, feeding from four air intakes which provide high maneuverability at the terminal phase.
