XX-Specific Sensor Changes-XX
Sphere and Hull Arrays—The sensitivity of the Sphere and Hull arrays has been increased relative to the Towed Array (to be clear, the TA is still much more sensitive in terms of long range performance) to better simulate their reported real world specifications. Also, the stern facing baffle of the Sphere has been increased to 120 degrees for active and passive modes, including the FFG and all AI platforms. It is not uncommon for contacts to show up on the broadband sphere before they show up on the narrowband sphere, and loud contacts will also show up more clearly on the sphere array broadband than the towed array broadband once both arrays have detected the contact. Expect to use the Sphere and Hull arrays more now to track and identify surface traffic and build situational awareness utilizing DEMON and TMA, and reserve the TA for finding and tracking those quiet hostile submarines or distant warships on narrowband. NOTE: Known Issue. It will be possible to see and hear contacts on the Sphere array before you can assign a Broadband tracker to them. You can immediately assign a narrowband tracker to all contacts on the sphere with a narrowband signature, although it is intended that generally contacts will be detected on the sphere broadband first. The broadband tracker issue is not intended, although it is present in stock DW as well, and the mod does not make it any worse in game play terms.
