LAKEHURST, N.J. – U.S. Navy avionics experts needed high-power amplifier units for the E-2D Advanced Hawkeye carrier-based surveillance aircraft. They found their solution from North Star Scientific Corp. in Kapolei, Hawaii.

Officials of the Naval Air Warfare Center Aircraft Division in Lakehurst, N.J., announced a $9.6 million order to North Star Scientific last week for 42 high-power amplifiers for the Navy E-2D fleet. The order includes engineering and engineering data support for high-power amplifier unit kitting, installation, and testing.

North Star Scientific will provide 13 high-power amplifier units for E-2D crypto modernization and frequency remapping aircraft retrofits; 10 amplifiers for E-2D tactical targeting network technology (TTNT) production aircraft; 10 spare amplifiers; five amplifiers for system configuration set-11 E-2C aircraft,; and four amplifiers for E-2D TTNT aircraft retrofits.
