During the 7th International Maritime Defence Show (IMDS 2015), in St. Petersburg, Russia from 1 to 5 July 2015, Russian Helicopters (part of State Corporation Rostec) is showcasing potential plans for the renewed production of the unique amphibious Mi-14 helicopter. This multirole helicopter can land and taxi on water, and also take-off from water.
Mi-14 helicopters were developed by the Mil Moscow Helicopter Plant and produced by Kazan Helicopters from 1973 to 1986. Both enterprises are a part of Russian Helicopters. Where there is interest from potential customers, the company is ready to upgrade the amphibious helicopter with the latest technologies and re-start production. This helicopter can significantly expand the range of search and rescue operations for the emergency services, and can also be operated by the Navy.
The Mi-14 was in service with the Navy and also operated commercially in Bulgaria, Cuba, East Germany, Ethiopia, Libya, Syria, Vietnam, Yemen, and Yugoslavia. Today these helicopters are in service with the Polish Naval Aviation.
The basic version of the helicopter was the antisubmarine Mi-14PL, and from 1979 the towing minesweeper Mi-14BT and multirole search and rescue Mi-14PS were introduced into service.
Amphibious Mi-14 helicopters are designed on the basis of the multirole Mi-8T helicopter. The main design distinction is that they boast hermetically sealed boat bottoms, instead of traditional helicopter undercarriages, enabling them to land on water. The sides are fitted with floats for stability, which also support the retractable landing gear. The Mi-14s other systems were also adapted for marine use, and numerous technical solutions developed for it later found application in Mi-8/17 helicopters, such as the Mi-8MT and its export variant Mi-17.

During the visit of Russian President Vladimir Putin to India, Russian Helicopters, a subsidiary of Oboronprom, part of Russian Technologies State Corporation, and Elcom Systems Private
Limited, part of the Indian investment conglomerate SUN Group, signed in New Delhi an agreement to set up in India a modern industrial facility for manufacturing of Russian helicopter models, namely helicopters of the Ka- and Mi- brands. The joint venture will have the capacity to produce key helicopter
units and carry out final assembly of the machines as well as engage in ground and flight testing. It is expected that the enterprise will start with production of components for the multirole Ka-226T helicopter. The enterprise will serve as an industrial base for hi-tech Russian rotorcraft products in India. “India is a traditional partner of Russian Helicopters in terms of helicopter deliveries. The creation of a joint Russian-Indian enterprisemarks a new stage and also a logical continuation of our joint efforts in light of the growing demand for Russian helicopter models,” said Dmitry Petrov, CEO of Russian Helicopters. According to Petrov, the joint venture will help drive the development of India’s aerospace industry and provide for effective application of advanced Russian technologies. It will also make it possible to organize the training of Indian engineers and promote the development of highly qualified personnel across the entire production chain. Moreover, the enterprise will be eligible to implement offset projects under various procurement tenders in India where Russian rotorcraft are involved. The holding company and Elcom Systems also reached an agreement on plans to create a joint Helicopter Academy in India for the training of flight and technical personnel. Vladimir Putin’s visit to India resulted in the signing of a set of documents aimed at strengthening military-technical cooperation between
Russia and India, including in helicopter manufacturing. India is a traditional buyer of Russia aircraft and presently has a fleet of 280 Russian-made helicopters.

The present-day combined arms battlefield has evolved to become increasingly demanding, as far as fast concentration of assets on the main axis of advance is concerned. Meanwhile, water and terrain barriers and obstructions exert a significant delaying effect on force projection, thus impeding the success of military operations in general. Therefore, in Russia a large family of engineering vehicles, specifically designed to effectively surmount various obstacles was developed. All equipment was made by one and the same design bureau, which maximized vehicles’ commonality in terms of fixtures and couplings, thus adding to their battlefield interoperability.
One of the best examples offered by Rosoboronexport is the MTU-90M armored vehicle launched bridge that can span a ditch, ravine or other gaps of up to 19 m. Boasting an armor protection comparable with that of main battle tanks, MTU-90M is used to lay single-span bridges during the battle in the face of enemy fire. Bridge removal is possible from both sides of the obstruction.
When bridging gaps with spans up to 40 m on forces deployment routes, the MMK mechanized bridge layer is used. The system includes vehicles to transport bridge elements and an assembly vehicle. The bridge is deployed by pushing elements along the level rail with their subsequent interconnection. MMK elements can be combined to launch bridges of 16, 22, 28, 34 and 41 m.
The TMM-6 heavy mechanized bridge layer allows deploying bridged to cross chasms, canals and water barriers with spans up to 100 m and depth up to 5 m. The bridge is laid by setting bridge elements in place one after another and interconnecting them. TMM-6 can be used to launch either one bridge across a 102 m gap, two 51 m bridges, three 34 m bridges or six 17 m ones. Rosoboronexport also offers the PTS-4 amphibious tracked carrier, capable of fording water barriers with a load of military hardware, personnel and cargo with the total weight up to 18 tons. The amphibian can cross obstacles with the current speed of 3 m/s. Moreover, it is also effective in SAR and emergency evacuation operations on water.
A much larger amphibious transport is the PDP ferry, taking aboard up to 60 tons of military equipment and carrying it across water obstacles with a current speed of up to 2.5 m/s. PDP is an engineering vehicle that consists of a three-pontoon ferry and a tracked carrier for transportation on land. The carrier’s specially designed wrench is used to load vehicles, which disembark on their own on the other side of the obstacle. The flat bottom and small draft allow operating the ferry in shallow waters.
The largest and the most versatile means of crossing obstacles is undoubtedly the PP-91 pontoon bridge that is used to launch a single-lane bridge with a span of 268 m, or a 168-m long 1.5 lane bridge, or a two-lane bridge out to 141 m to ensure two-way traffic. The max load of the pontoon bridge is 120 tons.
The Russian engineering solutions can help effectively accomplish missions associated with the engineering support of forces, crossing obstacles with spans up to 100 m and water barriers up to 268 m using pontoon bridges and ferries.
