Boeing [NYSE: BA] has shipped the Thuraya-2 mobile communications satellite from its Boeing Satellite Systems manufacturing facility in El Segundo, Calif., to the Sea Launch home port in Long Beach, Calif., where it is being prepared for an early June launch.

The satellite is the second spacecraft built and shipped by Boeing for Thuraya Satellite Telecommunications of Abu Dhabi, United Arab Emirates. The satellite will be lifted into orbit by a Zenit-3SL rocket from the Odyssey launch platform positioned on the equator in the Pacific Ocean.

Separately, Boeing announced that it has been awarded a contract from Orbital Sciences Corp. [NYSE:ORB] to provide linearized C-band traveling wave tube amplifiers (TWTAs) for the Telkom-2 satellite for Indonesia.

Orbital awarded the contract to Boeing Electron Dynamic Devices (EDD) located in Torrance, Calif. EDD is a leading provider of high reliability products for space and defense customers.

In communication satellites, TWTAs are used to amplify and transmit radio frequency signals back to Earth for a variety of applications including voice, video and data. On satellites that carry a large number of signals, a linearizer is often added to the TWTA to cancel the amplifier distortion.

On Tuesday, Boeing delivered previously ordered TWTAs to Orbital for use in three Galaxy satellites being built for the PanAmSat [NYSE: SPOT].
