While we are on the topic of the LCS... Here are some great documents with up-to-date LCS details and scheduling if you need it: http://www.mcaleese.com/sites/default/files/RDMLAntonio%20Defense%20Programs%20Conference_LCS%20FINALv2.pdf http://www.navsea.navy.mil/Portals/103/Documents/Exhibits/SAS-Morton-LCSMM.pdf {Correction June 7th} Correction from my previous post on the LCS. The TRS-4D and SeaRAM will get installed starting with LCS-17 and only be on Freedom-class variants following LCS-17 (e.g. LCS-19, LCS-21,LCS-23,etc..) Sorry about that. {End correction} All LCSs after LCS-17 (commissioning in 2019) will receive a rotating version of the C-band TRS-4D AESA as well as SeaRAM to replace the current Mk.49 RAM launcher on all freedom-class ships after LCS-17. From: http://www.janes.com/article/56339/first-trs-4d-radar-for-usn-freedom-variant-lcs-completes-factory-acceptance quote:
The first eight Freedom variant LCSs are being delivered with the Airbus Defence and Space TRS-3D/16 G-band radar, designated AN/SPS-75 in USN service. However, the remaining eight vessels - starting with USS Indianapolis (LCS 17) - are to be fitted with a rotating version of the TRS-4D system as an 'in-line' upgrade. Based on solid-state Gallium Nitride technology, TRS-4D is a software-driven radar employing full digital beamforming, and with pulse-Doppler processing in all beams. The rotator variant features a single-face AESA antenna rotating at either 15 rpm or 30 rpm (depending on the update rate required) at 2-70° in elevation. The use of an AESA array, with instantaneous dual-axis beamsteering in both azimuth and elevation, allows for 'backward scanning' to ensure fast-track initiation.

The SeaRAM is already installed on many of the trimaran hull Independence variants of the LCS and is slated to be integrated onto the Freedom variants starting with LCS 17. The VDS being talked about for the LCS ASW package is the CAPTAS-4 (the Type 2087 version) From: http://www.drs.com/media/3830/sna-brochure-vds-final-11jan2016.pdf quote:
The VDS Transmitter was selected by the U.S. Navy to meet the ASW Escort Mission requirement for the Littoral Combat Ship (LCS). From: https://news.usni.org/2016/01/20/peo-lcs-barred-from-deploying-early-version-of-anti-sub-mission-package quote:
The mission package includes a Variable-Depth Sonar – the Navy chose the Thales UK Sonar 2087, the same VDS used on the Royal Navy’s Type 23 frigate Info: https://www.thalesgroup.com/sites/default/files/asset/document/Captas-4.pdf Also for the ASW mission package will be a towed torpedo decoy called the AN/SLQ-61 Light Weight Tow (LWT). It is described as being a new derivative of the SLQ-25 Nixie decoy and will have 2 decoy sets aboard the ship, like the Nixie. From: http://www.mcaleese.com/sites/default/files/RDMLAntonio%20Defense%20Programs%20Conference_LCS%20FINALv2.pdfhttp://www.mcaleese.com/sites/default/files/RDMLAntonio%20Defense%20Programs%20Conference_LCS%20FINALv2.pdf quote:
ASW Capabilities • Local Detection (Variable Depth Sonar) • Area Detection (Towed Sonar/Helo/VTUAV) • Engagement (Helo) • Torpedo Defense & Countermeasures (Light Weight Tow) quote:
Variable Depth Sonar (VDS) (x1) – Multi-Function Towed Array (MFTA) (x1) – Light Weight Tow (LWT) Torpedo Countermeasure (x2) – Mission Planning, Execution Management, & Decision Support System (x1) – Support Equipment LWT Naming reference here: http://jobs.climber.com/jobs/Construction-Extraction/Norfolk-VA-23501-USA/Surface-Ship-Torpedo-Defense-SSTD-Technician/97611317#top quote:
Five (5) years of practical experience in the maintenance, troubleshooting and/or repair of systems/equipment similar in complexity to the Surface Ship Torpedo Defense (SSTD) Systems to include experience in design, engineering, assembly, integration, installation, documentation, testing, maintenance, repair, training and logistical support of SSTD Systems including the TWS (Torpedo Warning System), AN/ALQ-25 Nixie, AN/SLQ-61 LWT (Light Weight Tow), and emergent SSTD systems. The LCS ASW Mission package, which includes the previously mentioned VDS and LWT, is projected to reach IOC in 2018, but considerations are being given to ship availability so it would probably be safer to put it at 2019. From: http://www.navsea.navy.mil/Portals/103/Documents/Exhibits/SAS-Morton-LCSMM.pdf quote:
Initial Operational Capability projected for FY2018, subject to ship availability and operational requirements Thanks. If you need anymore information regarding this, let me know.
