Built by Space Systems/Loral (SS/L), the 1300-series hybrid spacecraft, weighing in at 4,642 kg (10,234 lb), carries 24 C-band and 24 Ku-band transponders, to provide a variety of services in the continental United States, Alaska, Hawaii, Mexico and Canada. An industry leader in power, performance and reliability, SS/L’s 1300 model is a space-proven platform that supports a wide range of satellite services and has an excellent record of reliable operation. Its high efficiency solar arrays and lightweight batteries are designed to provide uninterrupted electrical power. While this spacecraft is designed for a 15-year service life on orbit, Sea Launch’s direct insertion into equatorial orbit is expected to yield additional years of fuel life. Galaxy 18 will be positioned at 123 degrees West Longitude.
