Ultra Electronics and Sparton have secured subcontracts from their Erapsco / SonobuoyTech Systems joint venture to manufacture passive and active Sonobuoys in support of multiple underwater missions.

As part of this new development, Ultra Electronics USSI and Sparton De Leon Springs will receive $6.9m and $9.2m contracts respectively.

ERAPSCO / SonobuoyTech Systems recived this contract to deliver passive and active sonobuoys that are used for detection, classification, and localisation of adversary submarines during peacetime and combat operations.

Work under this contract will be performed at Ultra Electronics USSI’s facilty in Columbia City, Indiana, and Sparton’s De Leon Springs, Florida facility.

The sonobuoys can be deployed to assess environmental circumstances and help install top search tactics, as well as communication with friendly vessels.

"The sonobuoys can be deployed to assess environmental circumstances and help install top search tactics."

They are also capable of transmitting an acoustical signal source and accept underwater signals of interest, which are then delivered to monitoring units for analysis.

Recently, the US Navy recognised ERAPSCO Joint Venture as a Tier 1 superior supplier after the evaluation of evaluation of the past three years of contractor performance assessment reporting system (CPARS) data.

US Navy research, development and acquisition assistant secretary Sean Stackley earlier said: "This programme gives us the opportunity to acknowledge suppliers who made the extra effort and over a period of years consistently performed well."

The 2015 superior suppliers are recognised as firms that deliver the greatest overall value to the department in terms of cost, schedule, performance, quality, and business relations.

In May, Erapsco delivered sonobuoys production subcontracts to Ultra Electronics USSI and Sparton DeLeon Springs, worth $47m and $40m respectively.
