Helos check each other's decks
Indian and Australian air crews highlighted their navies’ interoperability during AUSINDEX in the Bay of Bengal on April 7.

An MRH-90 from HMAS Canberra and an MH-60R from HMAS Parramatta landed on the frigate Indian Naval Ship (INS) Sahyadri and the corvette INS Kiltan, while a Sea King from INS Sahyadri and a Chetak from INS Kiltan cross-decked to the Australian ships.

Parramatta’s Flight Commander Lieutenant Commander Damian Liberale said the procedure for landing helicopters on a foreign warship was heavily regulated.

“Before we flew, we physically visited each of the ships while alongside at Visakhapatnam,” Lieutenant Commander Damian Liberale said.

“We looked at the markings on the flight deck and took the chance to have face-to-face conversations with the Indian crews.

“Only then were we authorised to land on their ships.”

Parramatta’s pilots Lieutenant Jarrod Huisman and Lieutenant Mitchell Sanders flew their ship’s Seahawk ‘Warlock’ to Sahyadri and Kiltan.

“Landing is the tricky part, so we both had a turn on each ship,” Lieutenant Huisman said.

“All Australian ships use the same visual markings on their flight decks, but the Indian ships are different … there’s no circle, and the line-up lines are for different aircraft.”
“The Sea King was the biggest helicopter any of the current crew has seen land on Parramatta.”​
The pair performed “yoyo” landings and take-offs on each flight deck before returning to Parramatta, where they were guided down by flight deck marshaller Leading Seaman Aircraft Technician Avionics Aaron Lever.

“My job is to make sure it’s safe for the pilot to land and to liaise with the landing safety officer,” Leading Seaman Lever said.

“The Sea King was the biggest helicopter any of the current crew has seen land on Parramatta; it was a sight to see as it used up all of the flight deck’s operating area.

“The Chetak was really entertaining: the three crewies were squashed together on a bench seat like they were driving a Kombi van.

“They all gave me a wave as they flew away.”

Lieutenant Commander Liberale said both nations’ landing procedures were a variation of those used by NATO.
“We are now confident of operating to Indian flight decks,” he said.

“There are more similarities than differences between our two nations.”

AUSINDEX is a biennial bilateral naval exercise between the Indian Navy and the Royal Australian Navy.

The task group took part in the exercise during deployment on Indo-Pacific Endeavour 2019, which aims to deepen engagement and partnerships with regional security forces.

Commissioning of Indian Coast Guard Vessel C-441

A new Coast Guard vessel is commissioned by Chief Secretary, Government of Kerala Sri Tom Jose at Vizhinjam harbour, today, under the aegis of Regional Commander Western Region, Inspector General Vijay D. Chafekar. The function was witnessed by senior officers from Army, Navy, Air Force, BSF, Police, Airport Authority, Central & State Authorities and National Cadet Corps.

The function was conducted with full ceremony of parading the guard and band. Indian Coast Guard Ship C-441 is capable to undertake multifarious tasks such as close coast surveillance, interdiction, search and rescue and rendering assistance to boats and crafts in distress at sea and will enhance the search and rescue capacity of Kerala seas. The ship is commanded by Assistant Commandant Amit K Choudhary and has 13 crew onboard with specialisation in various fields.

Indian Navy to get 10 Ka-31 helicopters

07 MAY 2019

The Defence Acquisition Council (DAC) headed by Defence minister Nirmala Sitharaman has recently approved the Rs 3,600 crore ($5,198,400,000) proposal to buy 10 Kamov-31 AEW Helicopters from Russia for the Indian Navy.

Russian Navy Kamov Ka-31

The Kamov Ka-31 (NATO reporting name 'Helix') is a military helicopter developed for the Soviet Navy and currently in service in Russia, China and India in the naval airborne early warning and control role.

These helicopters are critical for the Indian Navy as they will help in increasing the radar coverage and will act as an extra set of eyes. The radars onboard the ships have a limited ‘horizon’, which are not able to track low-flying targets, in particular, anti-ship missiles. In 1999, the Indian Navy had ordered the Ka-31 AEW helicopters and they were deployed on board the INS Viraat aircraft carrier and other ships. There have been follow-on orders and so far there are around 14 Ka-31 helicopters in service of the Indian Navy.

These rotorcraft will join INS Vikrant, India’s first indigenous aircraft carrier that is currently under construction.

Endurance mode user trial of drdo Land-based Prototype (LBP) for Air Independent Propulsion (aip) System for submarines for a period of 14 days was successfully completed at Naval Materials Research Laboratory (NMRL), Ambernath, on 2 December 2017.

The aip, developed by Naval Materials Research Laboratory (NMRL) is a 250 kW Phosphoric Acid Fuel Cell (PAFC) based system, that allows up to 14 days of underwater endurance for a submarine running solely on power supplied by this system.

NMRL’s aip system incorporates a set of innovations that make it a rather contemporary system. For one, NMRL’s aip package has an onboard hydrogen generation plant, which produces hydrogen ‘in situ’ that too without any combusion, unlike many other aipconfigurations where hydrogen for a mission has to be carried on board in tanks.

PAFC has much longer service life than any other commercially viable FC type and has much better tolerance to impurities in the reactants used even when compared to polymer electrolyte fuel cells (PEMFC). But, PAFC operating temperatures are usually higher in comparison to PEMFC and overall power to weight ratio is lower.

The PAFC is designed such that series/parallel stacks can be used for power generation levels of up to 500 kw, this modularity of NMRL’s aip solution enable it to be used in submarines other than the Scorpene as well. This also naturally increases the survivability of the system, since even if one of the modules fails, the control system for the PAFC stacks can reconfigure the remaining operational units to continue to supply power output, albeit at a reduced quantum.

All info available about the DRDO AIP is at least a year and a half old. Got any thing new on it ?
 
The sight shown is for manual aiming of AF630. Each circle corresponds to 50m/s crossing valocity. You have to align the I piece with appropriate circle and put that on the target. This will ensure that the gun is aiming ahead of the target and rounds are fired at the future position of the target.

I do know that is the sights for the HMG too - But didnt know that this Mount too can control the AK630
