Novi indijski CTOL

Vrlo je izgledno da će novi indijski nosač zrakoplova imati osnovnu karakteristiku palube za konvencionalno slijetanje i uzlijetanje zrakoplova (CTOL - Conventional Take-Off and Landing) umjesto dosadašnjeg dizajna palube za kratko uzlijetanje na brodovima INS Vikrant i INS Vikramadityja (izvorni RFs Admiral Griškov).

Navedena se vijest može iščitati iz taktičko-tehničkih zahtjeva natječaja koji je objavila Indijska ratna mornarica za nabavu četiriju AEW&C (Aerborne Early Warning & Control) zrakoplova namijenjenih uporabi s nosača zrakoplova s katapultom.

Natječajem se implicira da se kod dizajna sljedećeg nosača zrakoplova nakon broda INS Vikrant (IAC 1), IAC 2 napusti koncept tzv. ski-jump platforme, iako uprava za mornaričke projekte još uvijek nije odredila konačan dizajn plovila. Procjenjuje se da će IAC 2 imati između 55 000 i 65 000 tona istisnine a gradnja bi trebala započeti nakon porinuća INS Vikranta u 2011. u brodogradilištu Cochin. Najoptimističnije su procjene da bi se novi nosač zrakoplova mogao naći u operativnoj uporabi 2015. iako se pretpostavlja da će to biti do 2020. Paluba CTOL dizajna rabi sustav lansiranja i povratka te se cilja na nabavu sustava EMALS (Electro-Magnetic Launching System) i AAG (Advanced Arresting Gear) koji su predviđeni za ugradnju na novi američki nosač zrakoplova Geral R Ford (CVN 78).

Tokom svečanosti u brodogradilištu "Kočin", u južnoj indijskoj državi Kerala, danas je u more porinut INS Vikrant, prvi indijski nosač aviona. Ovim činom Indija je stupila u elitni i ekskluzivni krug država koje su u stanju da samostalno konstruišu i proizvedu nosač aviona.

Nešto o klasi Vikrant sa Vikipedije.

Nekoliko fotografija sa priprema za porinuće:

Kako je to objavio Dnevnik HR

Vir: Dnevnik hr
http://dnevnik.hr/


INS Vikrant, brod od 40.000 tona, bit će operativan 2018. kada prođe niz ispitivanja. Označava ulazak Indije u uzak klub zemalja koje same projektiraju i grade svoje nosače zrakoplova, u kojemu su još Sjedinjene Države, Velika Britanija, Rusija i Francuska. Program je stajao oko 5 milijarda dolara, a realiziran je s dvije godine zakašnjenja.

>> VIDEO Ovo je najveći ratni brod koji je Japan izgradio od Drugog svjetskog rata

No 'ovo je važna etapa', istaknuo je ministar obrane A.K. Antony koji je sudjelovao na predstavljanju nosača u luci u Cochinu. 'Ovo je prvi korak dugog puta i prvi važan korak'. Po ocjeni analitičara, modernizacijom svog arsenala Indija želi sustići Kinu čiji se utjecaj širi. Nosač zrakoplova će biti stacioniran u Indijskom oceanu, kažu vojni stručnjaci.

New Delhi je uložio milijarde dolara u modernizaciju vojne opreme. Po ocjeni međunarodne mreže KPMG-a, zemlja će od 2010. do 2016. potrošiti 112 milijarda dolara na naoružanje. U subotu je vlada najavila da je za ispitivanje spremna prva nuklearna podmornica sagrađena u Indiji.

Svi ti programi imaju zadaću 'povećati moć Indije, istodobno s jačanjem diplomacije', drži Rahul Bedi, iz vojnog časopisa Jane's. Indija usto treba do konca godine dobiti od Rusije stari ruski ratni brod Admiral Gorškov, preimenovan u INS Vikramaditya.

Indija trenutačno posjeduje samo jedan nosač zrakoplova, britanski brod star 60 godina, koji je kupila 1987. i nazvala ga INS Viraat, koji će se u idućem razdoblju postupno povlačiti iz službe. (Hina)

Na listu zemalja sposobnih za gradnju nosača aviona treba dodati Italiju. Njihov "Garibaldi" izgrađen je u Tržiču (Monfalcone) i stupio u službu 1985, a "Cavour", izgrađen u Sestri Levante, stupio je u službu 2009.
Italija je pokušala izgraditi nosač aviona i za vrijeme WW2, pregradnjom putničkog broda "Roma", ali je kapitulacija 1943. omela dovršetak. Isprike, ako je malo Off Topic.

Indijska mornarica u procesu velike nadogradnje
 
PTI Photo
Datum objave:
26.11.2013

Načelnik stožera indijske ratne mornarice admiral Naval D.K. Joshi je rekao da je indijska ratna mornarica spremna za veliku nadogradnju vrhunskim tehnologijama kako bi poboljšala sigurnost indijskog akvatorija, prenosi indijski The Hindu.  Admiral Joshi je rekao kako će zemlja imati tri nosača zrakoplova do 2017.godine, a jedini trenutni nosač zrakoplova INS Virat će biti povučen iz uporabe do tada. Ispitivanja domaće balističke podmornice na nuklearni pogon započinje uskoro. Druga faza prvog domaćeg nosača zrakoplova INS Vikrant završila bi do 2017. "Ne postoji puno zemalja u svijetu koji grade vlastite nosače zrakoplova ili podmornice na nuklearni pogon", rekao je on .

Što se tiče podmornica, admiral je rekao da je došlo do kašnjenja u izgradnji podmornica klase Scorpion koje se grade u suradnji sa inozemnim partnerima u Mumbaiju. Izgradnja je sada u punom zamahu, a francuska tvrtka DCNS je rekla kako će stisnuti rokove, tako da podmornica bude ipak isporučena oko navedenog roka u ugovoru. Podmornice će ući u uporabu oko 2016, rekao je on .

Mnogo više podseća na Gorškova - Vikramadityu, ali je manji od njega. Ipak, ogromno je dostignuće graditi sopstveni nosač. Na oplati se vide neravnine - nisu Indijci još uvek majstori preciznog varenja. S druge strane, Srbija ima problem da skupi par desetina dobrih varilaca za Južni Tok, pa mi ne možemo to komentarisati.

Indijska ratna mornarica poslala RFP za izgradnju 65.000 tona teškog nosača zrakoplova

Datum objave:
20.07.2015

Indijska ratna mornarica je poslala 15.7. zahtjev za dostavu prijedloga na adrese četiri velika međunarodna brodograditelja u vezi sa projektom izgradnje nosača zrakoplova teškog 65.000 tona. Izgradnjom još jednog nosača zrakoplova ispunit će se cilj ratne mornarice za trećim nosače zrakoplova u floti.

Projekt će se provoditi u okviru domćeg programa nosača zrakoplova, koji je već u tijeku sa izgradnjom 40.000 tona teškog nosača, INS Vikrant kojeg gradi Cochin Brodogradilište. INS Vikrant se u sklopu projekta naziva IAC-1 te se planira njegova isporuka 2018. Nakon što uđe u sastav mornarice, zamijenit će INS Viraant, 28.700 tona teški nosač zrakopllova koji je kao rabljen nabavljen iz Velike Britanije još 1986.

Indijska ratna mornarica operira sa jednim od tri planirana nosača aviona, INS Vikramaditya, 44.500 tona teškim nosačem zrakoplova izgrađenog za vrijeme bivšeg SSSR-a koji je modificiran za potrebe indijske mornarice.

Indijski RFP poslan je na adrese Lockheed Martin, BAE Systems, DCNS i ruskog Rosoboronexporta.

Prema nekim informacijama Indija odustaje od gradnje trećeg nosača aviona za svoju mornaricu, dok se prema drugima razmišlja da li da taj brod bude građen u klasičnoj formi sa katapultom ili kao i dosadašnji sa ski džampom.

Indian Navy’s ‘Vishal’ Aircraft Carrier Officially Off The Table?
Shiv Aroor Feb 15 2020

Could India’s planned indigenous ‘flat-top’ aircraft carrier, designated the Vishal-class, be on hold — or at the very least, the subject of a formal rethink? A series of indications this week suggest that the Indian government may not be speeding towards the Vishal under the Indian Navy’s long-standing doctrinal pressures for a 3-carrier navy.

The navy currently operates the INS Vikramaditya aircraft carrier and will, within the next two years, induct the similarly configured Vikrant, the first indigenously designed and built aircraft carrier in the country. The Vishal, forward planned as a break-away from the traditional ski-jump fitted carriers, is proposed to incorporate a catapult-based launch system. The configuration of the Vishal has been the subject of much discussion and debate over the last decade, with key design decisions — like the decision not to have a ski-jump for aircraft launch — taken in just the last few years. But rumours of a rethink on how soon, and whether the Vishal program will be embarked upon is now up for question.

For starters, India’s first Chief of Defence Staff General Bipin Rawat provided an unmissable indicator in his first detailed interview since taking strength in the newly created tri-service chief appointment that involves long-term acquisitions and planning within the confines of highly squeezed budgets. In response to a specific question on aircraft carriers by News18 journalist Shreya Dhoundial, General Rawat said, “One aircraft carrier will be on the seas next year. You look at when do you really need a third one. If you get a third one, how many years will it take for it to develop? Even if you place the order for 2022 or 2023, it is not coming before 2033. Also, aircraft carrier is not just a carrier, along with it will have to come the aircraft. Where are the aircraft coming from? Along with that we will need the armada protection for that aircraft carrier. It does not happen overnight. It will be bought if it is required. But you cannot predict what the situation will be 10 years from now. We don’t know what will happen.”

His comments come in the wake of what has been a steady conversation on the Vishal, particularly over whether the ship would employ U.S. supplied EMALS (electromagnetic aircraft launch system) and reports in the British press claiming that the Elizabeth-class carrier’s blueprints had been sought by the Indian government in an effort to modify it for the proposed Vishal-class in an effort to reduce timelines. Running underneath these developments, however, there’s been unmissable sign that the Vishal was already a faraway castle, with no formal financial sanction from the Indian MoD, and a debate within government over whether a three-carrier navy was too much of an opulence in these financially strained times.

Another crucial indicator of the receding figure of the Vishal emerged earlier this month when Boeing revealed at the DefExpo 2020 show that it would shortly be testing its F/A-18 Super Hornet on a ski-jump platform at Naval Air Station Patuxent River, Maryland. Dassault Aviation, which, like Boeing, has so far conducted simulations of the Rafale on a ski-jump, could also look at proving the aircraft in a real test setting going forward, though there are no firm plans for now.

While it has generally been believed that the Indian Navy’s forecast requirement for 57 multirole carrier based fighters (MCRBF) were intended, at least in part, with the catapult-configured deck of the Vishal in view, the reality is actually significantly different. After conversations with the Indian Navy, Livefist can now confirm that the 57 jets being sought are fully and officially to meet the the combined requirement of INS Vikramaditya and the upcoming Vikrant/IAC1, in addition to a full shore-based training squadron. This position has been conveyed in discussions that the Indian Navy has held with both Boeing and Dassault.

Senior Indian Navy sources told Livefist, “The 57 deck based fighters (DBF) has is to meet the combined additional requirement of the current and next carrier, in addition to a training squadron we will be raising. Any conversation about aircraft for the proposed IAC2/Vishal will necessarily be only in the future.” The jets will be ‘additional’ to the MiG-29K jets that currently form the carrier wing on INS Vikramaditya — and will, according Indian Navy chief Admiral Karambir Singh two months ago — operate off the IAC1 as well.

Boeing’s move to prove the Super Hornet from a ski-jump has very much to do with the Vikrant/IAC1’s nearing date of entry into service. The company has, for years now, said it has conducted simulations to prove the compatibility of the Super Hornet with India’s current and next carrier.

Significant questions have continued to swirl, however, over whether the Super Hornet and Rafale are truly 100% compatible with the size, space and mechanical system configuration on the INS Vikramaditya and IAC1. This would pertain, among other things, to their hydraulic deck chocks and the busy deck conditions typical of Russian-influenced deck design, unlike the larger and very different configurations of the Nimitz-class and Charles de Gaulle that house the U.S. and French carrier jets respectively. It remains to be seen how the Indian Navy plans to navigate and address these incompatibilities as it moves forward on this acquisition program.

Earlier this month, the MoD updated Parliament on progresson the IAC1 thus: Major structural and outfitting work of Indigenous Aircraft Carrier (IAC1) has been completed. Major milestone activities including starting of Main Propulsion machinery and trials of Power Generation machinery have been completed. Trials of other ship’s equipment and systems are presently in progress. Ship’s targeted delivery was affected due to delay in supply of aviation equipment from Russia.

The IAC1 is expected to enter sea trials late this year or early next, with scheduled entry into service in 2022.

India’s first indigenous Aircraft Carrier INS Vikrant completes basin trials
By Dorian Archus -December 1, 2020

India has successfully completed basin trials of the indigenous aircraft carrier 1 (IAC 1) INS Vikrant, the official handle of Defence Public Relation Officer (PRO) for Kerala, under directorate of Public Relations of India’s Ministry of Defence, has announced.

According to official Indian MoD sources, the sea trials of the aircraft carrier are expected to start in early 2021. The basin trials were held at Cochin Shipyard Limited in Kochi. Their completion means that the aircraft carrier is now ready to start the sea trials.

“IAC1 project enters the final phase, sea trials expected early 2021,” PRO Defence Kochi said on Twitter.

According to India’s Defense Ministry, INS Vikrant successfully completed the pre-contractors sea trials in December 2019.

INS Vikrant :

The INS Vikrant is the first indigenous aircraft carrier design being undertaken by the nation of India. It is one of two planned vessels in the new “Vikrant-class” of surface warships and has seen construction begin in 2009. The Indian Navy’s first indigenous aircraft carrier Vikrant is currently under the third phase of construction.

INS Vikrant is a 260 meters long and 60 meters wide vessel displacing 37,500-tonnes. The maximum speed of the ship is announced at 28 knots, with a range of 7,500 nautical miles at a speed of 18 knots. INS Vikrant is set to receive a large crew complement composed of 160 officers and 1,400 sailors. The aircraft carrier will be able to accommodate up to 30 fighters and helicopters, including Mig-29K fighters jets and Ka-31 helicopters.

The Vikrant will be equipped with 4 x 76mm Otobreda dual-purpose cannons and backed by several surface-to-air missile emplacements. For short-ranged work against incoming aircraft or missiles, a digitally-controlled Close-In Weapon System (CIWS) will be installed. A Selex RAN-40L L-band early warning radar system will be part of the defensive network of sensor and systems processing.

Boing je uspešno prikazao mogućnost aviona F/A-18E/F Super Hornet da poleće sa nosača koji su opremljeni ski-jump palubom, a sve u cilju svoje promocije ovih letelica za RM Indije.

Quote

Boeing has released a video of its F/A-18E/F Super Hornet jet launching from a ground-based “ski jump” ramp, in a demonstration for India, which is looking to buy a new carrier-based multirole fighter. The Indian Navy’s current carrier, as well as its next flattop, lack catapults, which means the service requires a jet that can take off from a sloped ramp before returning to the ship using arrestor gear.

Boeing has been flying a Super Hornet from the ground-based ramp at Naval Air Station Patuxent River in Maryland for some time and you can read more about the program in this previous War Zone article. The same ramp has been used during testing of the short takeoff and vertical (STOVL) landing capable F-35B variant of the Joint Strike Fighter.

Sea Trials Commence for India’s Indigenous Aircraft Carrier ‘Vikrant’

India’s Indigenous Aircraft Carrier (IAC) named ‘Vikrant’ today embarked on its maiden sea-trial marking an important event in Indian shipbuilding. During the maiden sailing, ship’s performance, including hull, main propulsion, PGD and auxiliary equipment would be closely watched. The IAC Vikrant can carry a complement of MiG-29 K aircraft and KA-31 naval early warning helicopters. It can also host several other aircraft including India’s recently acquired Sikorsky MH-60R Helicopters. Locally made LCA Naval aircraft could also operate from the deck of the Vikrant.
