Honeywell ‘F-125IN Turbofan’ to power 125 IAF Jaguars

Honeywell ‘F-125IN Turbofan’ engine components

What will happen, if you are adding more components to an existing airframe without correspondingly increasing the engine power? Obviously, this will result in low thrust and other problems.

Jaguars first came to India (18) as a loan from British Royal Air Force (RAF), then 40 came from Warton, another 45 assembled at HAL plants in India so on and so forth. Jaguars participated in IPKF operations in SriLanka (1987-90), 1999 Kargil war etc. As the aircraft become older, India carried out many modernizations, especially in the 90s and in early 2000s. Now it’s the time for engine.

It is believed that with current modifications, Juguars life can be extended up to 2030. Honeywell F-125IN will provide higher thrust and reduce the life cycle maintenance costs. According to Honeywell, engine replacement doesn't need any structural modifications. After Rolls-Royce withdraw from the race, only Honeywell remained in competition for completely re-engine 125 Jaguars. On Monday, Indian Air Force issued Request for Proposal (RFP) for engines to Honeywell.

According to Honeywell, the benefits of using F-125IN Turbofan engines will be,

I. Enhanced mission capabilities:
a. 23% shorter high – hot takeoffs
b. 17-40% higher thrust
c. Greater mission range
d. Faster climbs to 20,000 feet without afterburner
e. 36% extended fuel range
  f. Increased combat survivability – auto re-start after flame out

II. Technical superiority with increased performance:
a. Drop-fit replacement
b. 555 pounds lighter than current aircraft configuration
c. 4,400 pounds greater high – hot takeoff payload
d. Decreased pilot workload, increased safety
e. Increased pilot safety – F124 – F125 has 500,000 hours without a loss of a single aircraft due to engine failure
f. Decreased pilot workload – Engine FADEC, EMS

III Improved reliability and reduced life-cycle costs:
a. Greater time between maintenance
b. 2,000 hours minimum time between overhaul
c. Lower cost maintenance
d. Reduced fuel consumption
e. Rupees 7,000 Crores (US$1.5 billion) in reduced life-cycle costs

Hope that without much time loss, Jaguars will be back on Indian skies.

The saga and the threat of Unmanned Aerial Vehicles (UAV)

The frequent strike of Drones in the Af- Pak tribal belt of South Asia is now-a-days not rare news at all. Drones are striking in this high density terrorist area on every now and then; and become a major threat to terrorist. As the earlier strikes were not fully depend upon the correct intelligence inputs, a lot of civilians are also died. But now a day the correct intelligence input reduced the damage to civilians and become a deadly weapon against terrorists.

The main advantage associated with these Drown strike is that it is(can be) comparatively cheap and will not result in any manual loss for the attacking forces. These vehicles are fully controlled and deployed by people sitting in the remote areas using their satellites and computers. Recently Pentagon decided to train more UAV pilots than that of the fighter pilots!!!

Many countries around the world are going ahead to build their own UAV's. In 2005 terrorist organization Hizbolla send a UAV to Israel towns which carry a camera. Even if it didn’t carry any weapons, the success of it was enough to create panic in the intelligence circles. The low flying, UAV which have a cool battery powered engine can escape from missiles, which are generally tracking the heat waves.

The irony is that the UAV which big farmers use for spraying pesticides in their lands can be used for carrying bombs and other weapons to big distances. Think about the situation when these UAV's are falling to the hands of terrorists. Destroying UAV's are also a costly business; its said that Patriot missiles can effectively destroy UAV's but the cost is $3mn/missile. Terrorists can build a dozen of UAV's on that cost.

Many countries are very rapidly advancing in this sector. If things are going in this way the future fighter planes will be unmanned only. UAV pilots will control the vehicle from the safe locations, using the advance satellite data and intelligence inputs. Moreover the cost will be low and no human losses to the attackers.

In this situation we have to develop our strategy for countering this new phenomenon. We have to accelerate the research on this field, and have to allocate more funds. Not only in building UAV's but at the same time destroying the UAV's which are targeting our nation. It’s possible that we may find a wave of UAV attacks in Kashmir and other border states in another 5-6 years, so have to focus on the low cost missiles to destroy
the UAV's too.

The defence ministry should not allow these critical projects to go in the way of Gorshgov, Scorpene and many other deals; where the cost and time escalation put a question in the projects success itself. As Hizbollah already succeed in achieving UAV, we can calculate how much time it will take for LeT and other terrorist organizations which are particularly focusing India to get these things.

Indian arms procurement policy and snails, who will win the race?

“The internal politics over the years is such that whatever defence requirements are cleared by the government, they are opposed by the opposition parties and the same happens when roles change and the opposition sits in government. That impinges very badly on our defence requirements. As far as defence goes, we don’t even match up with Pakistan,” Barbora, while referring to Defence exports, told an aerospace seminar organized in New Delhi by the CII.













[Malabar 2009]

The Barbora referred here is no other than our Vice Chief of Air Staff Air Marshal P K Barbora. Normally personals from armed services will not come in open space and criticize the policies of government. In such a background if Vice chief of IAF made a public statement on this issue then anyone can imagine how much critical the issue is.

In fact there is no need to argue on whether India need more artillery, fighter aircrafts, submarines or not. The reasons are well known. In fact India's "highly friendly neighbors" will increase their military potential to the maximum extend they can under any circumstances. And we have one of the most bloody borders in the world. In fact we fought war in the eastern(Bangladesh Liberation war), north and north east(Indo - Sino war), west (Indo - Pak wars).




















[A picture from Kargil war]

Apart from this there are many insurgent activities with in India like Maoists(who already have presence in approximately one third of the country), illigals militias of north east, Terrorism in J & K, and random terrorist attacks in other part of the country. In many cases these people are fighting with security forces using their advanced weapons, all time favorite AK 47 to the latest guns, LMGs etc visible in Hollywood films.

There is only two ways to get the modern weapons. Either we have to develop it or buy it from other countries. But the main problem to attached to developing arms in India is the long development cycles, some projects in defence sector is taking decades to show result. Some times it will achieve target or we simply buy the necessary weapons from outside in wake of urgency.

The main problem to secure cutting edge defence technology is the high price tag attached to it. Any country will think twice before buying machines like F22 Raptor, B2 Spirit etc. Thanks to our developing economy we have funds. We have funds(even if it may not be enough for a maga shopping always) to buy or develop it. As a usual exercise we are allocating funds for defence purchases.












[IAF Aircraft over Chenab river]

But what happens later? Armed forces will identify requirements, and submit the proposal to the government. So far good. Later we will float the tender, shortlist the defence firms, make the trails accross all the terrains, then negotiate on price and bought the weapon and train the personals to use it.

But after the proposals stage we will take a long time to float the tender, more time to short list. In some cases we will float the tender again short listing again, the long time negotiations on price. At this point of time some politicians will accuse the government about corruption. Some one will file a case in Supreme Court. And our long legal procedure will start. In the mean time the accused company may be blacklisted, and the project stalled. After sometime we may again open the cold storage and show some lights to the old proposals. But by that time requirement may be changed. As long as we have 'n' number of parties at any time to oppose the government, most of the time we will have accusations over defence purchases even if it is right or wrong. And except in rare occasions investigation will took years to complete.

Continuous saga of delay in defence contracts, Army's struggle with choppers

Due to fear of future accusations, now a days purchase order files are moving with snail's pace or even dead. And after blacklisting many companies there may be 1 or 2 company remains in many sectors. Remember that the worlds of arms market are not run by angles.
\
I don’t understand the problem with FII and private sector firms in Indian defence sector. What the problem with FII when we are buying the arms itself foreign companies? As long as there will be strict guidelines for FII and the investments are in the companies/places in India I don’t see any problem at all. What about private companies? Why government have problem about the private sector's entry to core defence sectors? After all they are Indian companies working under the guidelines of GOI. Anyone thinks that Lockheed Martin, Boeing, General Electric, Dessault etc are pure government companies?

In my opinion we should develop a process model for defence purchase, and stick to it. We should precisely define a framework and guidelines for purchasing arms. From requirement gathering phase on wards, set a time line and completely obey it. The framework should define what we have to do in each and every phase, and paying a premium for cutting edge technology is not bad. Build a specific professional team for arms purchase and make direct contact with top arms manufacturers. At the same time make it sure that if we bought a weapon, spare parts will be available for it in the future.

It’s our duty to give most advanced weapon in the hands of soldiers protecting our borders in time. In a time when our  internal and external security threats are rising; multiplying our capabilities should be a high priority task.

Continuous saga of delay in defence contracts, Army's struggle with choppers


[AƩrospatiale SA 315B Lama - Known as Cheetah in India]

How many defense contracts are signed on time in India? And how many executed on time? Anyone submitted a request according to RTI act on this issue? It is a naked truth that a vast country like India which have not so friendly neighbors and constant floods on different parts of the nation requires a powerful and dynamic support from air. Many parts of India are inaccessible through land and many border posts of the army are heavily depended on air for survival.

The story is not different for people caught in floods and forces ho lead the campaign against Maoists in the deep forests.

Choppers are widely used for transportation of materials and humans to the remote parts and inaccessible terrains. Everyone knows that every machine have successful working time. Did you heared about any machine continuously working for ever?

Army uses Cheetah(AƩrospatiale SA 315B Lama) helicopters for material transportation and causality evacuation at an astonishing heights of 20,000 feet or more. The sad fact is that these choppers are of 1970 vintage, already completed approximately 40 years in service.

The 3,000 crore tender for the procurement of 197 choppers(133 for army rest for Air force) canceled after finding discrepancies. Then new tenders are issued. According to the procedures after floating tenders government will invite companies for field trails - summer trials, winter trials, validation trails etc.

But government is yet to invite any company for trails moreover Bell pulled out of the contract citing the offset clauses. Even if trails started in next year the new helicopters will not arrive before 2013-14. 5 critical years after the scheduled time.

Remember that these choppers are the lifeline of thousands of troops deployed across high altitudes. What is the problem with us? Now a days deals after deals are delayed, postponed or re tendered. Aircraft carriers, Trainer aircraft and many other programs suffered the same fate.

What will happen if suddenly a war started? Who will support the troops in high altitudes? 40 year old Cheetahs? Who will provide the food and ammunition to the troops in border?

Government have to make swift decisions on these issues. These are high priority tasks which cant be postponed.

Suryakiran team should not be disbanded


[Suryakiran Team]

Talks are on the air about the disbanding of one of the prestigious assets of Indian AirForce -Suryakiran Aerobatic team. After the formation of team in 1996 this 'Bidar air force station' based team have performed from Dal Lake in the north to Thiruvananthapuram in the south. Abroad 'suryakiran' also performed in Srilanka, China etc.

The reason for disbanding is the shortage of trainer aircraft in the air force arsenal. The currently employed trainer aircraft for pilots - HPT-32 is grounded following crashes and other technical failures. So in order to continue the pilot training program IAF don't have enough aircraft. So they are forced to disband the team and move all the HJT 16 kiran aircrafts to pilot training section.

It is said that usually 140-150 pilots are on training in HPT-32 aircraft at any given time. Then they will move on to other aircraft for further training. Now HPT-32 is down, next in line to be grounded may be the other aircraft series which are infamous for mechanical failures.

In the '90s, according to its own submissions in Parliament, it lost 80 pilots and 185 aircraft. Which makes it almost a squadron a year or a fourth of its entire fleet in the past decade alone. And the estimated loss: Rs 6,800 crore.

According to an old estimate "The IAF loses one MiG fighter every 2,500 flight hours, making it one of the most vulnerable machines in service with any force in the world"

They may find a temperory solution by disbanding the Suryakiran team. But what will they do next? Recently Air Force celebrates 77 years of service, after these much years are we reached in such a situation where we don't even have enough aircraft to train our pilots?

When this 42,000 crore MRCA deal will be finalized and start delivering? Even if it is finalized the shortlisted aircrafts Rafale, Typhoon, F16 C/D, F/A-18E/F, JAS 39 Gipen, MiG35 all are combat aircrafts, not the trainer one. The deal for 66 Advanced Jet Trainers(AJT) is one of the most procrastinated deals in aviation history. IAF projected requirement in 1984 but deal signed only in 2004, 20 years of delay. The deliveries of BAE Hawk Mk 132 finally started in 2007 , within that time may be the fighter aircraft gone one generation further.

The sanctioned strength of IAF is 39.5 squadrons, with an healthy level at 44 squadrons, but currently India doesn't have that much squadrons. For power projection over South Asia and Indian ocean region IAF requires much more squadrons. MRCA deal is good one but not enough, moreover further delays will be disastrous.

Suryakiran aerobatic team performed very good in skies, if Suryakiran will able to participate in foreign airshows it will be better for both IAF and India. What administration have to do is not disbanding the team but allow it more opportunities and bring in new trainer aircrafts for IAF. I don't want to see news like "IAF aircraft crashed; pilot killed" in the front pages. We already lost many promising pilots and trainers not any more. Replace the fleet...
