Israel has been building up its surveillance capabilities to monitor enemies such as Iran, whose nuclear program it sees as a major threat.
The satellite, called Ofek 16, was shot into space early Monday morning from a site in central Israel by a locally-developed Shavit rocket, which was used to launch previous Ofek satellites.
"We will continue to strengthen and maintain Israel's capabilities on every front, in every place," said Defense Minister Benny Gantz.
The Defense Ministry called Ofek 16 "an electro-optical reconnaissance satellite with advanced capabilities."
The first images will be received in about a week.
State-owned Israel Aerospace Industries [ISRAI.UL] was the main contractor for the project and the satellite's payload was developed by defense firm Elbit Systems.
