  1. Welcome everyone, Green here bringing you my second forum of the series on the UK Royal Navy. Today we are going to have an in-depth look at the UK class 23 frigates. The Type 23 class is the largest class of frigate constructed for the Royal Navy since the 26 ships of the leander class. Like the leanders they type 23 provides the back bone of the Royal Navy's anti sub frigate force, and with any luck should continue to do so for many more years. The ships where designed to complete that role in the rough waters of the North Atlantic using their towed array sonar. The Type 23 where the first stealthy ships to enter service in the Royal Navy with hull angled off the vertical to reduce a radar signature. After the Falklands war Harpoon anti-ship missiles and a 144 mm gun where added to give the design a better punch. The ships will also receive the new powerful towed sonar 2031Z which equips the ten of the class. This sonar will allow the ships to find much quieter modern submarines that may operate in inshore waters in the future. Further studies are in hand to find ways to extend the lives of these large and capable vessels and further enhancing their military capabilities.

  2. Frigate class F125 - A new ship for new tasks New framework: The Bundeswehr Concept sets out the framework for the development of the armed forces. Missions to international conflict prevention and crisis management, including the fight against international terrorism, determine the structure and equipment of the Bundeswehr. As a result, the armed forces are categorized into engaging, stabilization and support forces. Stabilization forces operate in stabilizing peace missions of long duration in multinational joint. Their tasks include enforcement of embargoes, the monitoring of sea and air space and the support of evacuation procedures. The Navy followed in terms of transformation of the Bundeswehr, the aim of developing the maritime capabilities of the Bundeswehr operationally focused. To meet the requirements in the Marine stabilizing peace missions with an innovative type frigate, with the previous ships has little in common. The conceptual differences range from the type of effectors (weapons) to use parameters such as duration and crew size. The task profile requires completely new approaches in business organization and in the technical design. Improving the armed forces joint combat effectiveness: In the center of the conceptual claims, is the armed forces joint combat effectiveness to increase significantly. Characteristic of the new F125 frigate type therefore are able to: Capacity for tactical fire support from sea to land (land of targets) Ability to use special support and specialized forces (eg evacuation operations), Ability to network-centric warfare with land and air forces and Prolonged availability in the field. Flexible options for action: For use in stabilization operations through a novel sensor-weapon approach to flexible policy options will be provided. Taking the basic qualifications for the permanent monitoring of sea areas need F125 selective, graded and precise action skills that match the operating environment. The ability to in any position by use of appropriate means can act both as a de-escalating escalating is crucial. In addition, F125 marked protective and active capabilities against asymmetric threats received. Protection generated here from information superiority, rapid, flexible response options on board and a suitable ship construction. There are also automated monitoring systems on board as well as the expansion of the direct monitoring area of the ship at anchor in the harbor and through the use of boats and underwater drones. This sector in particular requires intense study and application of coordinated approach, in order to achieve an effective and technically manageable concept. The mission required flexibility to be supported by capacity for embarkation aboard helicopters, special forces, with bar association leaders, naval forces as well as protection through the integration of several boats statement. Intensive use and two crew concept: From the requirement for a long-lasting availability in theater also follows a fundamentally different technical, logistical and economic interpretation of the ships. What is required here is an up to two-year time bar of the ship in the mission area without a scheduled shipyard repair or return to home port. This technique, known as intensive use concept of the F125 frigate requires in comparison with the service units located in the Navy to double the operating hours of the repair phase. The increased availability of vessels follows - because of not increased at the same way staff requirements - the need for a new crew concept. What is required is the design of the vessel for a man about 100 full crew which will be replaced in the four-month intervals, in theater (two-crew concept). The doubling of the operating hours of these approaches, along with significant reduction of staff due for maintenance, operation and use of the vessel for additional technical solutions. Automation and the technical interplay of various equipment and systems gain in comparison to the current lifestyle, labor-intensive operation, a new and much bigger role. So far in the construction of naval ships pursued approaches are not suitable. Conclusion: With the F125 frigate it is therefore in no way thinking about a successor for existing vessels, but the consistent implementation of altered conditions in a large maritime projects. Currently, there are no maritime platform designed for the beginning of tasks is shown. It will not arrive in F125 forward to realize everything that is technically possible. Rather, the industry is called upon to combine the technological possibilities to the concerted, required capabilities into an overall design.

  4. Canadian Navy: Frigate - Halifax Class About the Ship http://www.navy.forc...igate_3_0_0.jpg The first of an eventual twelve Canadian designed helicopter-carrying frigates. They combine traditional with systems to deal with surface and air threats as well. The HALIFAX class are the work-horses of the Canadian Navy task group concept. Launched: 1992-1996 Speed: 29+ knots Endurance: 7,100 nautical miles at 15 knots (diesel) / 4,500 nautical miles at 15 knots (turbine) Complement: 225 (including air detachment) Range: 9,500 nautical miles Interior Bridge: http://www.navy.forc...igate_0_0_0.jpg The ship is navigated and steered from the bridge. It is always fully staffed when the ship is at sea. From here, the Officer of the Watch gives commands to the helmsman, the lookouts, and the communicators and coordinates various activities around the ship. Operations Room: http://www.navy.forc...igate_0_1_0.jpg This is where the captain fights the ship. From rows of computers processing constant real-time information streams into a coherent tactical picture, HALIFAX combat systems teams engage their formidable array of defensive and offensive weapons to protect their ship and the other ships of the task group. Machinery Control Room: http://www.navy.forc...igate_0_2_0.jpg Here, the MCR team keeps the ships power flowing from the engines to the shafts and all the electrical and mechanical systems in the ship weapons, sensors, communications, lighting, air-conditioning/heat, refrigeration, fire-control, pumps, winches and a host of other power hungry components. Directly beneath the MCR in the engine room itself, the 50,000 shp generated by twin Pratt and Whitney gas turbines push the ship to more than 29 knots (50 km/hr) while the variable-pitch screws can stop within her own length. Engine Room: http://www.navy.forc...igate_0_3_2.jpg Beneath the MCR, in the engine-room, the 47,500 shp generated by the twin General Electric gas turbines can push the ship to more than 29 knots (50 km/h). For normal cruising, the 20-cylinder 8,800 hp Pielstick diesel is used, giving the ship extended cruising range. Armaments and Countermeasures BOFORS 57 mm Naval Gun: http://www.navy.forc...igate_1_0_0.jpg This dual -purpose (anti-aircraft and anti-ship) 70 calibre (length of barrel) 57 mm automatic gun equips Halifax class frigates. It is housed in an unmanned plastic turret, which produces a low radar cross-section. The turret, which is 2.6 m high, 6.3 m long and 3.4 m in width, is controlled from a panel in the combat information centre by an operator. The system also features a stabilization system which uses rate gyros to detect ship movement and to provide stabilization orders. As well, the hydraulically operated loading system for the Mark 2 is an automated one. When the loading procedure is complete there are 120 rounds in the turret. Shield II Decoy System: http://www.navy.forc...igate_1_1_0.jpg Shield II is a microprocessor-controlled, fully automatic missile decoy system capable of deploying both chaff and infrared munitions. In the face of a threat, Shield selects the most appropriate response from its memory using data obtained from onboard sensors such as radar and electronic support measures or ESM. To counter threats with a dual-mode capability both chaff and infrared decoys can be deployed automatically. The system can operate fully automatically although both manual and local control from the bridge is possible. Halifax class frigates and Iroquois class destroyers are equipped with four six-barrel launchers per ship. MK 48 SeaSparrow (GMVLS): http://www.navy.forc...igate_1_2_0.jpg The Seasparrow missile is operated from the Mk 48 Mod 0 vertical launch missile system. The system is designed to provide hemispheric coverage, a higher rate of sustained fire power and increased reliability in a flexible, modular system which requires lower manning levels. On 'Halifax' class ships, two eight- canister launchers are deck-mounted amidships adjacent to the funnel (Note: the Canadian frigates can carry 28 cells). The length of each launcher is 4.78 m. This weapon equips Halifax class frigates. With a speed of M 2.5 and a 16 km range, it uses semi-active radar for guidance. In the front is the guidance and control section which includes a digital computer. Immediately behind is the warhead (a 38.6 kg WAU-17/B blast fragmentation warhead using a dual-purpose proximity/ impact fuze which can be used against high- and low- altitude targets). The target is detected by the ship search radar and designated through the combat information centre. Prelaunch data and firing commands are relayed to the missile which is then launched. The missile thereafter follows a proportional guidance path directly to the intercept point (it begins by rising to a height of approximately 4 m and then turnovers to the correct azimuth for interception). Mk 141 HARPOON (SSM): The Harpoon missile is fired from the Mark 141 Mod 1 launcher system at a maximum rate of one every two seconds. Each Halifax class frigate is equipped with two launcher systems (a launcher system possesses four launcher-containers). 2 x MK 32 Torpedoes (SVTT): The Mark 32 is a launcher system for lightweight anti-submarine torpedoes and consists of the torpedo tubes themselves, a removable breech mechanism which houses the high-pressure impulse air flask and an associated air supply system. The mounting is usually on the ship’s weather deck and may be trained up to 45. The system may be locally or remotely operated with, amongst other types of torpedoes, the Mark 46 (the Mark 46 is part of the Canadian Navy’s anti-submarine warfare or ASW armoury). The Mark 32 launcher system equips Halifax class frigates and Iroquois class destroyers (2 twin tubes / frigate and 2 triple tubes/ destroyer). PHALANX 20mm (CIWS): This weapon’s gun assembly consists of a 20 mm M61A1 Vulcan Gatling-principle gun. The M61A1 Vulcan is a six-barreled weapon capable of phenomenally high rates of fire (3000 rds/min). The entire system is capable of dealing with high-angle driving missiles. It also has surface engagement capability. This latter characteristic was developed to meet a perceived requirement for a high-volume-of-fire weapon to engage small high-speed, highly-maneuverable boats, helicopters and low-performance fixed-wing aircraft. The system equips Halifax class frigates (1/ship), Iroquois class destroyers (1/ship) and Protecteur class replenishment ships (2/ship). 50 Calibre Machine Guns: The M2 .50 machine gun (MG) has been used both for surface engagements and air defence since the Second World War. This air –cooled weapon tends to be used in patrol, mine countermeasures, landing, riverine and major auxiliary vessels and, as such, equips the Kingston class MCDVs (2 MGs/ship). However, larger warships such as our Navy’s Halifax class frigates, Iroquois class destroyers and Protecteur class replenishment ships have them as a regular part of the ship’s armament (8, 6, and 6 MGs/ship respectively). The M2 .50 MG has a practical rate of fire of 550 rds/min. Sea King Helicopter: This shipborne helicopter is capable of ASW, surface surveillance and support. In these roles, it is carried by escort ships and replenishment ships (Halifax class frigates carry 1 helicopter, Iroquois class destroyers carry 2 and Protecteur class replenishment ships carry 3). The Sea King's operational speed is 203 km/h. Its service ceiling is 5,150 m and its range 760 km. It is equipped with two Mk 46 Mod 5 torpedoes and can carry 12.7 mm MG's. Some of these aircraft have been modified for Forward Looking Infra-Red or FLIR (typically a fixed-direction narrow field of view system, with a display for the user). Sensors AN / SQS-510 Sonar System: The AN/SQS-510 (V) is a medium-frequency (2 to 8 kHz), hull-mounted or variable depth, and active sonar system. It provides for the rapid detection and localization of active and broadband passive contacts. The system is installed on the Halifax class frigates in a hull-mounted mode and on the Iroquois class destroyers in both hull-mounted and variable depth sonar (VDS) configurations. In addition to normal blue water operations, this sonar is optimized for performance in three specific scenarios: shallow water submarine detection, mine avoidance and torpedo detection. Its range scale is 1,835 to 55, 045 m. SIGNAAL SPG-503 (STIR 1.8): Halifax class frigates are equipped with two such systems. Range: 140 km for 1 square meter target. (STIR = Signaal Tracking and Illumination Fire Control Radar) RAYTHEON SPS-49: The AN/SPS-49 is a very long-range two-dimensional Air Search radar designed for use as the primary aircraft detection radar onboard the Halifax class frigates. ERICSSON SEA GIRAFFE: This G-band Air/Surface Search Radar is capable of providing accurate tracking data to the ships Combat Information Center and weapons systems. AN / SQS-510 CANTASS: This passive, critical angle low-frequency towed array sonar system equips Halifax class frigates. This system provides frequency and bearing analysis of acoustic emissions from long ranges and is consistent in both shallow water and beyond the second convergence zone. Data is presented to the operator on programmable CRT displays in a variety of alternative formats. Audio data is presented as a further aid to detection and classification. Class Data Overview: The first of an eventual twelve Canadian-designed helicopter-carrying frigates. They combine traditional Canadian anti-submarine capabilities with systems to deal with surface and air threats as well. The HALIFAX class are the work-horses of the Canadian Navy task group concept. Launched 1992-1996 After decades of unrelenting anti-submarine warfare (ASW) activities in the North Atlantic during the Cold War, the navy's long-range strategy evolved, in the 1980s and '90s, to encompass a broadened, more general purpose role, in keeping with the changing nature of contemporary threats to world peace and stability. Incorporating many technological advances, including an integrated communications system, a command and control system, and a machinery control system, these vessels' weapons, sensors and engines form a formidable platform of defensive and offensive capabilities. They are quiet, fast, and have excellent sea-keeping characteristics. Ships for Canada's 21st Century Roles In the mid-nineties, HMCS HALIFAX took up her station on patrol in the Adriatic Sea, as part of NATO's Standing Naval Force Atlantic, to enforce United Nations sanctions against the former Republic of Yugoslavia. Soon after, HMCS VANCOUVER sailed to the other side of the Pacific to join multi-national exercises in waters off Hawaii and underscore the increasing importance of Canada's interests in Pacific Rim regions. These marked a turning point in the history of the Navy. Today, HALIFAX class frigates deploy singly or as part of a task group anywhere in the world -- with NATO, US carrier battle groups, or in concert with other allied vessels. These deployments are measures of other nations' confidence in Canada. They would not be possible without our fleet of modern, versatile patrol frigates. Improved War-fighting Capabilities HALIFAX class frigates carry a formidable array of weapons and sensor systems including 8 Harpoon long-range, surface-to-surface missiles, 16 Sea Sparrow surface-to-air missiles, a Bofors 57mm rapid-fire gun, a 20mm Phalanx anti-missile close-in-weapons-system (CIWS), 8 x 12.7mm machine guns and 24 anti-submarine homing torpedoes. In addition, the ships can defend themselves using infrared suppression, Shield decoys, chaff, flares, a towed acoustic decoy, and radar and sonar jamming devices. The ship's torpedo-carrying helicopter significantly extends its range of operational effectiveness.

  5. Frigate "Sachsen" class (124) A total of three ships of the "Sachsen" class gives the Navy available. The type of ship - the "Sachsen" - was born on 4 November 2004 put into service. The commissioning of the last ship, the frigate "Hessen", took place in April 2006. Besides the "Sachsen" and the "Hessen", the "Hamburg" is set in December 2004 in the service. Frigate "Sachsen" (F219) The units of the "Sachsen" class frigates are designed as multi-purpose board with helicopter escort and area security. They have replaced the native to Kiel 103 B class destroyer. The home port of Wilhelmshaven units. The ships are since 9 January 2005 with the 123 in second class frigates Frigate Squadron summarized. Voher formed the "Sachsen" Class own squadron, the 1st Frigate Squadron. From 27 June, the frigates of the newly formed Flotilla 2 will belong. Sensors and effectors are optimized for the main functions of these vessels and association management association air defense. As with the frigate "Bremen" - and "Brandenburg" class is used to board the helicopter extensive Seezielbekämpfung and antisubmarine warfare. With the inflow of "Sachsen" class has the Navy on a particularly versatile and assertive naval warfare.
