Tests of the FOX micro-missile using inert configurations – without explosives – have made it possible to verify flight trajectories and validate simulation models, in preparation for forthcoming test campaigns.
AERTEC has carried out a new series of firing tests on the FOX micromissile at the El Arenosillo Experimentation Centre (CEDEA), which is part of the National Institute of Aerospace Technology (INTA), in Huelva. The tests, carried out using inert (non-explosive) configurations, form part of the system’s qualification process and have enabled the team to verify its in-flight performance with different inert configurations, as well as to prepare the necessary resources and procedures for the final tests.
The programme is currently in the qualification phase, as part of the company’s plans for 2026, and is awaiting the award of the contract for its final phase. The next planned campaigns will include laser targeting and live missile firings, using missiles fitted with warheads (explosive).
The campaign has focused on two objectives: executing pre-determined flight paths and verifying the accuracy of the simulation models developed by AERTEC for the aerodynamic actuators – the mechanisms that enable the missile’s trajectory to be altered. During the test firings, the guidance, navigation and control (GNC) system transmitted the necessary instructions to the actuators to follow the programmed trajectories. According to AERTEC’s assessment, the results showed a highly satisfactory correlation between the actual and simulated trajectories, which provides valuable information for preparing the next round of tests.
The tests have also demonstrated the usefulness of the data collected using AERTEC’s telemetry systems and INTA-CEDEA’s instrumentation for future campaigns. In terms of safety, the campaign has served to validate and optimise the procedures for protecting personnel involved in the tests. The experience gained will help to define the safety measures for the end user’s operation of the system.
A guidance system developed in-house
FOX is a micro-missile weighing approximately three kilograms, designed by AERTEC to provide precision strike capability from aerial platforms, particularly unmanned aerial vehicles. It combines inertial navigation during the mid-course phase of flight with terminal guidance via a semi-active laser seeker – also developed by the company – which enables the missile to be directed towards a target illuminated by a laser designator.
The programme forms part of AERTEC’s work in guidance systems and smart munitions. This area of activity includes the BAT guided glide bomb, which weighs less than 16 kilograms, as well as launchers and munitions management systems. The company also has the capability to integrate these solutions into manned and unmanned aircraft.
