Launch by Ariane 5 ECA in 2004 Mar with dummy satellite. XTAR is on an EADS-CASA 1194H payload adapter and a 5.8m Sylda 5C. The medium fairing, with an ACY5400 +2000 cylindrical extension of 2m, is used. Total V521 payload mass is 8297 kg including the two adapters and Sylda (totalling 917 kg extra).

The ECA is 4.71m high 5.46m diameter with mass 19t, including 14.6t of prop. It carries the 950 kg 1.13m high 5.46m diameter VEB (Vehicle Equipment bay).

The EADS/Les Mureaux H173 is 31m long 188.3t full 14.2t empty.

The USA registered XTAR-EUR with the UN, even though ownership is mostly Spanish. Spainsat, launched later, carries the XTAR-LANT payload.
