This paper reports on niobium Josephson effect array oscillators have been fabricated and tested. These devices deliver about 1 {mu}W of power, in the submillimeter wave range, to 20--60 {Omega} load resistors. The present upper frequency limit of about 500 GHz appears to be set by losses in the superconducting microstrip. Data on the submillimeter wave surface impedance of the niobium microstrip and details of the trilayer junction processing, which gives value of V{sub m} at 2K up to 800 mV, will be presented.
