The CH-148 will be operated by the Canadian Forces Air Command. It can conduct anti-submarine warfare (ASW), anti-surface warfare, surveillance and control, search and rescue (SAR) missions. It will also provide tactical transport for national and international security missions.

The helicopter has been developed under the Canadian Forces’ Maritime Helicopter Project (MHP). The project provides scope for the acquisition of 28 new, fully-equipped CH-148 Cyclone helicopters along with a long-term in-service support program. It will also provide 12 C-RAST helicopter haul-down systems for Halifax class (HFX) ships to accommodate the CH-148 Cyclone.

Orders and deliveries

In November 2004, Canada’s Department of National Defence placed a C$1.8bn contract with Sikorsky to produce 28 helicopters, with the first aircraft delivery expected in January 2009. The first production aircraft completed its maiden flight in November 2008. It arrived at CFB Shearwater in February 2010. The deliveries are delayed due to restrictions by US International Traffic in Arms Regulations.

The first 19 of the 28 CH-148 Cyclones will be supplied in interim standard rather than at the original contractual specifications. Maintenance and aircrew personnel will conduct initial operational testing and evaluation of the interim helicopters prior to deployment. The fully compliant helicopters will be delivered in 2012. All interim-standard helicopters are to be retrofitted and delivered to DND/CF by December 2013.

The German navy is also planning to replace its current fleet of Sea King helicopters with Cyclone helicopters.

Canadian Air Force expecting CH-148 Cyclone project completion in 2025

The Canadian air force faces an issue as their order of 28 new CH-148 Cyclone helicopters from Sikorksy Aircraft has been projected to only be completed in 2025. Earlier agreements had said that the order of the new fleet would be done by 2022. This new addition in time creates a problem as the new fleet will only arrive seven years after the retirement of the CH-124 Sea King helicopters, which have been operating for over 50 years now. This leaves the Canadian military woefully short.

Fortunately, the country’s navy fleet is also lacking, having to retire two supply ships, two destroyers, one Tribal destroyer ship was let go due to budget cuts and now a fourth warship is about to be retired. As reported by the CBC, if the navy carefully plans their resources, they might have enough helicopters between them.

An initial deadline was 2008 but Sikorsky Aircraft missed that deadline. In 2013 they began to rethink their decision to replace their fleet, but stuck with their decision and announced the retirement of the Sea Kings due in 2015. Another deadline given was 2018 for the arrival of their new fleet, yet this too was not met. Instead they were promised 12 operational helicopters with the basic operating systems in place by 2018, with the remaining 16 coming in between then and 2021. Then remaining four years will consist of training personnel and getting the fleet operational by government standards. Source @helihub.com

Design and features

ch-148-1

CH-148 is a military variant of the Sikorsky S-92 helicopter. It features a composite aluminium airframe with lightning-strike and high-intensity radio frequency pulse protection. It incorporates a wider four-bladed articulated composite main rotor blade in comparison with the S-70 Blackhawk. The tapered blade tip is angled downward to cut down noise and increase lift.

CH-148_148807_37802.jpgThe CH-148 main rotor head is a fully articulated hinge-less design with elastomeric bearings and automatic blade folding.- Image @b-domke.deS-92A_OY-HKA_30118.jpgMain rotor blade viewed from lower aft – Image @b-domke.deCH-148_148807_37985.jpgThe CH-148 tail rotor is a bearingless composite flex-beam design.- Image @b-domke.deft-opinion-ch148-cyclone-aew-daly-lgImage @casr.ca

The helicopter can operate with modern high-tech naval frigates and is equipped with numerous safety features. Flaw tolerance, bird strike capability and engine burst containment are integrated into the design.

Avionics

143354_800

CH-148 is equipped with APS-143B radar, the SAFIRE III EO System, L-3 HELRAS sonar and Lockheed Martin AN/ALQ-210 electronic support measure (ESM) system. Its aircraft management system (CMA-2082MH) is provided by CMC Electronics.

SENSORS 

APS-143B radar

an_apr143

ELEPHONICS radar.  The AN/APS-143(V)3 is a maritime surveillance and tracking radar designed for installation in a variety of fixed-wing aircraft and helicopters. It is also known as OceanEye. The system uses frequency agility and pulse compression techniques and consists of three units: an antenna, receiver/transmitter and signal processor. Radar control is via a dedicated control panel with on-screen controls, or by a central universal keyset via MIL-STD-1553B databus. Features include TWS for 30, 100 or 200 targets, air search with MTI, integrated electronic support and Mark 12A IFF system interfaces and electronic ECCM provision (including sector blanking and staggered pulse repetition frequencies).

The flat-plate planar antenna array, which can be fitted into any radome, is stabilized for ±30° in pitch and roll. The transmitter is a TWT (travelling wave tube) type with a peak power output of 8 kw and operating in the X band. The latest variant, APS-143B(V)3, can be upgraded with a complete imaging capability: range profiling, ISAR, spotlight SAR, strip-map SAR. The system can also incorporate software interfaces, via an embedded Tactical Data Management System (TDMS), for external systems such as FLIR, ESM, IFF and TDL. The TDMS capability also includes overlay of worldwide Database II or vector shoreline maps onto the radar display.

The internal, fully integrated Mark XIIA IFF interrogator has been designed to be compatible with the IFF interrogators being supplied for the US Navy’s MH-60R LAMPS helicopter, the Canadian CP-140 Aurora upgrade program, and the US and International Air Force’s AWACS platforms .IFF Mode 4 helps the Cyclone crew sort out cooperative sea and air targets in target-rich littoral regions.

MK 46 torpedoes

01_Context_image.jpgfc8172d7-1a03-4ae2-b8d0-254a813018b7Original

Torpedoes are self-propelled guided projectiles that operate underwater and are designed to detonate on contact or in proximity to a target. They may be launched from submarines, surface ships, helicopters and fixed-wing aircraft. They are also used as parts of other weapons; the Mark 46 torpedo becomes the warhead section of the ASROC (Anti-Submarine ROCket) and the Captor mine uses a submerged sensor platform that releases a torpedo when a hostile contact is detected. The three major torpedoes in the Navy inventory are the Mark 48 heavyweight torpedo, the Mark 46 lightweight and the Mark 50 advanced lightweight.

The MK-46 torpedo is designed to attack high performance submarines, and is presently identified as the NATO standard. The MK-46 torpedo is designed to be launched from surface combatant torpedo tubes, ASROC missiles and fixed and rotary wing aircraft. In 1989, a major upgrade program began to enhance the performance of the MK-46 Mod 5 in shallow water. Weapons incorporating these improvements are identified as Mod 5A and Mod 5A(S).

BRU-14/A weapon/stores rack

bru-14

The BRU-14/A bomb rack is a parent rack which provides for suspension and release of stores weighing up to 2,000-2,200 pounds. Two suspension hooks provide for attachment of weapons or stores having 14-inch suspension lugs. It connects to the aircraft special weapons release and control system to provide primary release, IFOBRL (in-flight operable bomb release lock) actuation, auxiliary unlock, secondary release, and mechanical arming of a weapon/store. Linear Electromechanical Actuator consists of a spring-loaded plunger that is mechanically locked and electrically released, thereby initiating hook release. Aero 1A adapter assemblies may be added to increase the bomb rack to 30-inch suspension capacity. The BRU-14/A is a modified Aero 65A bomb rack which has been adapted for use with P-3C and S-3A aircraft.

Major components consist of a linear electromechanical actuator and an in-flight operable bomb rack lock auxiliary release assembly.

The linear electromechanical actuator consists of a spring-loaded plunger that is mechanically cocked and electrically released to provide the force that initiates hook release. The auxiliary release assembly provides a secondary method of release should the linear electromechanical actuator or its electrical system fail.

Sikorsky_CH-148_Cyclone_Canada_028.jpgImage @grubbyfingersshop.com

The in-flight operable bomb rack lock mechanism consists of a remotely controlled bomb rack lock and emergency release auxiliary unlock. The IFOBRL consists of a lockbar, which pivots on the frame to lock the rear link in latched position, and an actuator assembly, which can be locked or unlocked manually. The auxiliary unlock assembly is a cartridge-actuated device providing a mounting point for the aft end of the IFOBRL. When actuated, the unlock releases the IFOBRL and allows it to move forward, freeing the rear link from restraint. Mechanical arming of a weapon/store is accomplished through two electrically actuated arming solenoids, which are mounted in the frame assembly. The BRU-14 is capable of suspension and release of a weapon/store in either an armed or safe condition. An electrical impulse from the aircraft is used to release the store. Mechanical arming is provided for more and/or tail arming. During ground operations and in flight the IFOBRL provides a positive lock to the release mechanism.

The left inboard, left outboard, and right weapon pylons on the Navy’s Light Airborne Multi-Purpose System (LAMPS) Mark III SH-60B Seahawk accommodate BRU-14/A weapon/stores racks. The BRU-14A bomb racks interface with the MK-50 Advanced Lightweight Torpedo (ALWT) and Penguin missile. Fittings for torpedo parachute release lanyards are located on the fuselage aft of each weapon pylon. Effective on BUNO 162349 and subsequent, the left and right inboard pylons have wiring and tubing provisions for auxiliary fuel tanks. All pylons have wiring provisions to accommodate the MK 50 torpedo. The left outboard weapon pylon can accommodate a missile launch assembly (MLA) which is used to mount the MK 2 MOD 7 Penguin air-to-surface missile. Source @globalsecurity.org

Countermeasures

The helicopter is fitted with sensor equipment to search and locate submarines during ASW missions. A modern countermeasures suite is incorporated to defend the helicopter against incoming missiles.

ATK AN/AAR-47 missile warning system

images (1)

The AN/AAR 47 basically works with an digitized and integrated warning system that is in turn integrated to the communication module of the pilot or the control command of the platform. The AN/AAR 47 is an radar based warning system.

The main feature of this system is to provide timely warning against Infrared MAN Portable Air Defence System (MANPADS). Detecting a MANPADS is an extremely demanding task and these MANPADS do not signal their presence till the launch of the missile, they do have a detectable radiation since they do not rely on active IR, radar guidance or a laser designator. These fire-and-forget systems and lock on and engage a target, speed to the target and destroy it in seconds. But these systems however, have a very small but still visible radar signature and also since propelled by propellant a IR signature. But this signature can be visible only for a very short period of duration. To counter these missiles if the old counter measures are to be used they may be hampered by the decisions of a pilot. But if the counter measures are integrated with the MAWS the system automatically deploys the flares without any delay thereby saving the platform from a possible attack.

The AAR-47 missile warning system consists of 4 Optical Sensor Converters (OSC), a Computer Processor and a Control Indicator. A single optical sensor converter is positioned towards each side of the aircraft and is integrated with an infrared camera which can detect any incoming missiles. With the space on a aircraft being very limited the whole size of the component has to be extremely compact and yet powerful the AAR-47 is a very compact system and is around 32 pounds and takes very negligible space on board a aircraft.
