Luís Carrero Blanco (March 4, 1903 – December 20, 1973) was a Spanish admiral and statesman.
His political career reached its zenith in June 1973 upon being named Prime Minister of Spain and made a top deputy to Franco. It seemed as though it was only a matter of timed before he would succeed the ailing dictator.

Within about six months of being named prime minister, he was assassinated in Madrid by four Basque members of ETA, who carried out a bombing while he returned from mass in an armored car. ETA placed one ton of explosives in a tunnel they had excavated under the street, which was definitely more than enough to assassinate Carrero. The blast catapulted the vehicle over the church it was parked in front of, and it landed on a second floor balcony on the other side. Because of this, Spanish people joke that Carrero was the first Spanish astronaut.
