TOS B was the second operational APT satellite. Launched from Vandenberg by Delta E at 1732 on 1967 Jan 26, it reached a 1328 x 1443 km x 102.0 deg orbit at 1750. ESSA IV was declared operational on 1967 Feb 8, replacing ESSA II, but on Dec 6 of the same year its cameras failed. The satellite was afterwards used for engineering tests.
