'Trumpet-F/O-2' 1, 2

The spacecraft are probably the next generationt for the Trumpet and 'Trumpet-F/O' SIGINT satellites operating in a Molniya orbit. As no name is known, these are referred here as "Trumpet Follow On 2".

These satellite most likely use a large, unfurlable dish antenna to collect the signals.

A official reported, that, although the satellite shares the same name with its precedessors, it is nearly 90% different in terms of technology.

'Trumpet-F/O-2' 1 is the host for the SBIRS-HEO-3 early warning sensor.

Secondary Payloads

'Trumpet-F/O-2' 1 (or NROL 35) is the host for the SBIRS-HEO-3 early warning package.

'Trumpet-F/O-2' 2 (or NROL 42) likely carries the SBIRS-HEO-4 early warning package.
