• Spain chose the Airbus A321 for three new SIGINT aircraft under the Santiago II program, restoring a capability lost when its Boeing 707 retired in 2014.
  • Airbus and Indra hold a €16 million study contract, with the full program estimated at about €436 million.
  • The larger A321 can carry a heavier mission system than bizjet-based rivals, and will complement Spain's Predator B drones fitted with SOAR.
