Designed for all-round defence against simultaneous air attacks from multiple targets, the Ezpata-IR missile is the first vertically launched infrared-homing surface-to-air missile, also the first IR-homing missile to use lock-on-after-launch. Upon launch, the missile flies to a lock-on point, following on-board inertial navigation. The missile then activates its two-colour IR-seeker and locks on. Target updates are received via data link, enabling the missile to counter evasive manoeuvres by the target.
The Ezpata has a set of tail-mounted, aerodynamic control fins, as well as thrust vectoring vanes in the motor nozzle, allowing for 40 g manoeuvring. The system's 3-D fire-control radar enables simultaneous engagement of eight targets for the naval version. The missile uses a low-smoke propellant to avoid detection.
Extended range versions (Ezpata-ER) are in development. They will feature a rocket booster and IR or Radar seekers.
This variant of the Ezpata-IR was recently developed for the Eusko Itsas Gudarostea. It has a more advanced seeker-head algorithms for differentiating between the target and background clutter often found in and around the Caribean archipelago. Because of the improvement in the seeker head, the newer version has a more efficient flight path allowing for an increase in range of 3km; a new maximum range of 15km.
IMSYS has stated its intention to end production of the Mk1 and continue with Mk2 version of the missile, as a part of the missile's overall growth path.
The radar-homing version's range is extended to 25km and has a higher operational ceiling 12000m. It is also 65kg heavier and 98cm longer than the IR version.
