Currently the Sonar 2076 which is in use in HMS talent is a submarine sonar and all 12 subs follow on will have their own sonars, also Thales has S-cube sonar suits for scorpene which can be used and this can be used in Scorpenes suits as Thales is the contractor, But I dont see an oppertunity here for that Sonar.
Have no doubt -
2076 is the best Sub-SONAR suite right now & if offered for our next line subs . It would be an cutting edge tech .
Infact the newer Block5 upgrade of 2076 is a gen ahead of Scorpene CUBE Sonar .
Biggest benefit to us will be open architecture and fast but economical COTS processors ,
BAE system claims processing power of more than 400 Laptops for version 4
Latest model have converted this Sonar suite from tactical system to complete Combat management system
Seeing the vision of Indian Navy , I feel IN can always enhance these further .
Infact open architecture will ensure easy addition of more algorithms for SAR imaging .
If I am not wrong then Perhaps these UK subs have -
Largest numbers of hydrophones (i.e Array size) , Very large arc of Passive/Active coverage and perhaps best Array to noise sensitivity for better clutter rejection .
Hmm not a bad idea to use these arrays to make sure not even the quietest subs in Indian Ocean remain hidden (MESMA/AIP you know .... ).
Sonar 2087 is a version of teh same sonar that can be used in Surface ships.
No different from 2076 - actually no of Towed arrays are vastly different , Freq , Arc, Sensitivity is all variable .
But Imo -
We don't really need a surface Sonar system .
Our very own indigenous
HUMSA is an class apart Sonar itself -
Its ultra low-frequency towed-array (ATAS) has very high processing capability & excellent sensitivity for noise rejection against anti-submarine warfare (ASW).
Combine HUMSA on ships with Ka-series/MRH shipborne naval helicopter equipped with active long-range (hull-mounted, towed-array and dipping) sonars , all provide the necessary standoff safety & required mobility .
Only problem with HUMSA is short range and Ping , which can allow Agousta with Sprint tactic to run away from detection of hull mounted HMS-1,hMS-2 HUMSA sonar . That is where combined network warfare of P8,Shivalik,Arihant,Scorpene,Ka-31 will come in handy .
