The boats are designed by State Research and Design Shipbuilding Centre (SRDSC) of Ukraine and being built by PJSC Leninska Kuznya Plant, headquartered in Kiev, Ukraine.

They are intended to conduct patrols in harbours, rivers, lakes, territorial waters and isolated areas. Other missions include protection of borders and river ports of Ukraine, assistance to aircraft or vessels in distress, and combating illegal migration, piracy and smuggling in the Danube river and the waters of the Black Sea-Azov basin.

The boats can also be deployed in UN peacekeeping missions.

Gurza-M boats construction

Keels for the first two armoured artillery boats in the Project 58155-class were laid in October 2012, after which the project was frozen for approximately two years.

The Ministry of Defence of Ukraine awarded a state contract to PJSC Leninska Kuznya Plant to resume the construction of the two boats in October 2014. The vessels were launched in November 2015.

A state contract for the construction of the next four Gurza-M-class armoured artillery boats was signed in March 2016. Keels for four artillery boats were laid in April 2016.

Project 58155 artillery boat class design and features

The Gurza-M armoured artillery boat’s engine compartment, weapon stores and wheel house are built using bullet-resistant steel materials.

The overall length and beams of the boat are 23m and 4.8m respectively and the maximum draught is 1m. The boat has a full load displacement of 54t and is manned by five crew members.

The wheel house, located amidships, provides unobstructed view through square windows fitted in the front and sides.

An integrated bridge system located in the wheel house provides a centralised monitoring of onboard sensors, electronics, propulsion system, and navigation and communications systems.

The boats can also be fitted with weapons and sensors as per the customer’s requirements.

The forward and aft sections of the boat are fitted with a BM-5M.01 Katran-M remote-controlled naval combat module, manufactured by Mykolayiv Mechanical Repair Plant. Each turret is fitted with two 30mm automatic grenade launchers.

Armament of the boat also includes a 30mm ZTM-1 automatic gun, 7.62mm CT machine gun, and laser-guided man-portable air-defence systems (MANPADS).

The ZTM-1 automatic gun can be fired at enemy aircraft flying at low altitudes, light armoured infantry combat vehicles, and dismounted soldiers.

The vessel is also armed with two Barrier anti-tank guided missiles (ATGMs) to fight against stationary and moving light-armoured objects, helicopters and modern armoured combat vehicles, fitted with explosive reactive armour (ERA).

Equipped with a tandem warhead, the ATGM can engage targets at a distance between 100m to 5,000m.

30 mm grenade launcher

The AGS-17 automatic grenade launcher (Avtomatichesky Granatomet Stankovy — mounted automatic grenade launcher) has proved to be an efficient infantry close fire support weapon. II is designed to kill enemy manpower and thin-skin weapon systems in the open or behind various covers. In addition to the tripod-mounted infantry version, there are also models designed to be fitted on helicopters, armoured boats, remotely controlled platforms of fortified area pillboxes, and armour.
     The AGS-17 fires 30 mm VOG-17M (designed by Bazalt) and VOG-SO rounds (developed by Pribor) fragmentation rounds with impact fuses. The Tula-based КBP Instrument Design Bureau developed the new GPD-S0 enhanced range and accuracy round in the early 2000s. A better ballistic coefficient of the grenade reduced its flight time, natural dispersion, and wind age.
     The AGS-17 is fed by a 29-round metal belt, stored in an ammunition box attached to the right side of the receiver. The launcher combat crew carries three ammunition boxes.
     The automatic grenade launcher is blow-back operated. The trigger assembly provides for both single-shot and automatic fire. The AGS-17 features a simple design and a high reliability in any operating conditions.

Saab will make India net exporter of fighter jet if it wins single-engined jet contract

Will make India net exporter of fighter aircraft: Saab

By IANS | Updated: Dec 09, 2016, 03.19 PM IST

NEW DELHI: Swedish aerospace major Saab says it would set up a brand new production line in India if it wins an Indian Air Force (IAF) contract for single-engined combat jets and would make the country a net exporter of such fighters — once the necessary procedures are in place.

“I think we are the only one right now who is developing brand new next-generation fighters. Even if we are single-engine, we have capability matching any of the other twin-engine aircraft that would be on the market,” Jan Widerstrom, Chairman and Managing Director of Saab India, told IANS in an interview.

Saab has fielded its next-generation Gripen E fighters in response to a communication to global manufacturers for their offer for what could be up to 100 jets.

The Gripen, in fact, was among the six jets in the running for an IAF tender floated in 2007 for 126 medium multi-role combat aircraft (MMRCA). The bulk of these aircraft were to be manufactured under licence in India. After protracted trials, the choice was narrowed down to two and then to one — Dasault Aviation’s Rafale. With the price negotiations going nowhere, the tender was eventually scrapped and the IAF opted for an off-the-shelf purchase of 36 Rafales.

The final contract was inked only in September 2016 and the jets will begin arriving in September 2019, with the order expected to be completed in 30 months.

Meanwhile, the IAF has also decided to purchase an additional 83 of the indigenously developed and manufactured Tejas light combat aircraft (LCA) when its original intent was to induct only two squadrons (36 aircraft).

In the midst of all this, the IAF has seen its strength dwindling from the sanctioned 42 combat squadrons to 25 — with the best it has achieved being 39.

This is largely due to the phasing out of Soviet vintage Mig-21s, MiG-23s and Mig-27s and the unserviceability of many aircraft due to the lack of spares after the collapse of the Soviet Union. Hence the latest proposal to purchase in the region of 100 jets.

These aircraft are expected to be manufactured in the country under the Make in India initiative.

“We are ready to offer full technology-transfer and build-up capability in India not only for manufacturing and production,” Widerstrom said, adding:

“We are not planning to move an old production line to India. Our offer is to build a brand new production line for the next generation fighters and the next after that. This will be putting India on the aerospace map as a net exporter of fighters.”

There is, however, a catch. The export of lethal weapons and systems is a rather gray area, with the Defence Ministry only recently setting in motion the process through which this could be done. Given that India took 25 years to purchase an advanced jet trainer and that the process for the Rafale has taken almost a decade, this could be a prolonged exercise.

Widerstrom was unfazed.

“We would definitely like to see India as a regional manufacturing hub for Gripen global orders in the future. We will fully comply with the Indian government’s regulations on export of defence equipment.” The company believed the aircraft “would certainly be a good fit for India’s requirements”.

“Our business model is to work through partnership with countries and companies. We have the full backup of the Swedish government on this,” Widerstrom noted.

“India will be part of our global supply chain. We have a European hub in Sweden. We are building up a hub right now in South America in Brazil, supporting that part of the market. What we want here in India is a third hub supporting this part of the market,” said Widerstrom.
