All three LIGO gravitational wave detectors have reached their design sensitivities. A sky-averaged detection range (SNR > 8) of more than 15 Mpc for gravitational waves emitted from inspiral binary neutron stars with masses of 1.4 M⊙ has been achieved with the two 4 km instruments. The fifth LIGO science run started in November 2005 and ended in September 2007. A full year of triple coincidence data has been acquired. The duty cycle of a single instrument was between 66% and 79%. Results from previous science runs are presented.
