Under the terms of the $35m contract, Cobham will deliver RF Microelectronics for the programme.
Work on the contract will be carried out by the company at its facilities in San Jose and San Diego, US.
Cobham Microelectronic Solutions senior vice-president and general manager Andy Graven said: "By leveraging our deep expertise in radio frequency (RF) technologies, we are able to provide our customers with high levels of technical performance in demanding environments.
"We are especially proud of our track record of on-time deliveries and solid program execution. Our assembly, inspection, and test automation processes enable us to deliver electronics with a very high level of reliability."
The company’s EW programme is aimed at providing self-protection capability against surface-to-air and air-to-air radar guided threats.
The EW solutions help detect, identify and manage electronic countermeasure responses to radar threats.
In December, Harris secured a $54m indefinite delivery / indefinite quantity (IDIQ) contract to supply the US Naval Research Laboratory with EW technology, as well as engineering services for the advanced decoy architecture project (ADAP).
Under the three-year contract, Harris will provide ADAP payloads designed to divert missiles from their intended targets with advanced electronic techniques.
