Raytheon to sup­ply MS3 for ACTUV pro­gramme


Raytheon Com­pany (RTN) was awarded a sub­con­tract from Sci­ence Ap­pli­ca­tions In­ter­na­tional Cor­po­ra­tion (SAIC) to de­liver its first fifth-gen­er­a­tion medium fre­quency hull­mounted sonar sys­tem as part of the De­fense Ad­vanced Re­search Projects Agency (DARPA) anti-sub­ma­rine war­fare con­tin­u­ous trail un­manned ves­sel (ACTUV) pro­gramme.

Ac­cord­ing to the US Navy, 43 na­tions op­er­ate more than 600 sub­marines; the steady in­crease in un­der­sea ves­sels makes track­ing a chal­lenge. Raytheon’s mod­u­lar scal­able sonar sys­tem (MS3) will in­te­grate into SAIC’s pro­to­type tri­maran ves­sel as the pri­mary search and de­tec­tion sonar. The sys­tem is de­signed to pro­vide search, de­tec­tion, pas­sive-threat fil­ter­ing, lo­cal­i­sa­tion and track­ing ca­pa­bil­i­ties with­out re­quir­ing hu­man op­er­a­tion.

MS3 en­ables anti-sub­ma­rine war­fare (ASW) and un­der­sea war­fare with ca­pa­bil­i­ties such as ac­tive and pas­sive search, tor­pedo de­tec­tion and alert­ment, and small ob­ject avoid­ance. Data from mul­ti­ple sonars may be fed to a cen­tral com­mand and con­trol node, pro­vid­ing a com­mon op­er­at­ing pic­ture as part of the ASW mis­sion. By in­te­grat­ing a host of ca­pa­bil­i­ties in a sin­gle sonar sys­tem, Raytheon de­liv­ers an af­ford­able so­lu­tion that ad­dresses crit­i­cal naval chal­lenges.

“His­tor­i­cally, manned sonars were cen­tral to anti-sub­ma­rine war­fare mis­sions. How­ever, the grow­ing num­ber of sub­marines travers­ing the world’s oceans makes this model un­sus­tain­able,” said Joe Biondi, Vice Pres­i­dent of Ad­vanced Tech­nol­ogy for Raytheon’s In­te­grated De­fense Sys­tems busi­ness. “By lev­er­ag­ing Raytheon’s her­itage in de­vel­op­ing un­der­sea sen­sors, MS3 can be con­fig­ured to pro­vide the ca­pa­bil­i­ties re­quired for ASW in an au­tonomous en­vi­ron­ment.”
