The Aljaba was originally developed in 1982 by a company Ц Kynos Ц which normally builds civilian construction equipment and had not until that point built military vehicles.
The Aljaba 8x8 developed in 1982 by a company Kynos SA, was the predecessor of a SHE Cavallo truck . ZF semi-automatic gearbox with torque converter.
The Spanish Ministry of Defence provided some funding and one prototype and three pre-series vehicles were produced. The Spanish Army carried out field trials with one vehicle in May 1985, near Toledo. The first two production vehicles were delivered to the Spanish Marines during mid-1987 with another vehicle going to the Spanish Army in the same year. In total some 10 vehicles have been delivered to Spanish Armed Forces.A single vehicle with a Spanish-produced four-axle semi-trailer was supplied to the UAE for extensive trials, although no orders have yet been placed.It is understood that prior to its liquidation, Kynos SA received an order for Aljaba tractor trucks from Iran. No vehicles are known to have been produced or delivered.
This Aljaba was selected by the South African National Defence Force (SANDF) as their tank transporter, named the Cavallo.
Since 2003 all assets, technology and orders of the Kynos SA were taken over by Group Servicios Y Proyectos Avanzados SPA company and the same truck is produced under SHE brand.
