Since the Indian Ocean tsunami of December 26, 2004, the landing platform dock (LPD) and the amphibious assault ship (LPH) have emerged as an instrument of soft power, with their on-board fleets of multi-purpose utility helicopters, landing craft, and air-cushion vehicles; plus their command-and-control capabilities and cavernous holds proving to be invaluable for disaster relief, small-scale policing or mass civilian evacuation operations. At the same time, the LPDs and LPHs have today emerged as invaluable tools for undertaking asymmetric warfare (against pirates in the high seas), expeditionary amphibious campaigns (such as those undertaken by the Royal Navy in 1982 to retake the Falklands Islands), and low-intensity maritime operations involving vertical envelopment tactics, which the Indian Navy (IN) calls "effecting maritime manoeuvres from the sea".
It was in the September 2004 that I had penned an analysis on the need for the IN to urgently begin planning for acquiring a modest fleet of no less than three LPHs for it to undertake both humanitarian relief operations within the Indian Ocean Region (IOR) whenever required, as well as prepare for the prospects of undertaking power projection-based expeditionary amphibious campaigns with its own integral naval infantry assets (as opposed to the still existing flawed practice of transporting a mere mechanised battalion of the Indian Army (IA) on board large landing ship tanks (LST-L). It, therefore, came as no surprise almost four months later when Navy HQ, headed at that time by Admiral Arun Prakash, the Chief of the Naval Staff, directed the Directorate of Plans & Operations to begin preparing the NSQRs for procuring a fleet of LPHs with a great sense of urgency. However, matters did not move swiftly enough on the procurement front, despite the articulation and unveiling by Navy HQ of its doctrines for effecting maritime manoeuvres from the sea though joint amphibious warfare operations. This, however, did not deter the Navy from setting up—on June 24, 2008—its Advanced Amphibious Warfare School and Fleet Support Complex--in the enclave that will come up along the beach road on the outskirts of Kakinada, about 500km from Hyderabad, in the state of Andhra Pradesh. It is here that the Navy is quietly but progressively raising its first of three naval infantry battalions (to eventually become a Brigade-strength formation), which will be trained and equipped to undertake both amphibious and vertical envelopment air-assault operations.
On the procurement front, matters began to move only in October 2010 when the Cabinet Committee on National Security accorded approval to Navy HQ to begin drafting the Request for Information (RFI) regarding the acquisition of four LPHs and related hardware under the 'Buy and Make Indian' clause of the Defence Procurement Policy (DPP-9). Under this clause, the Ministry of Defence (MoD) can invite proposals (based on a capability definition document) from those Indian shipbuilders from both the public sector and private sector that have the requisite financial and technical capabilities to enter into joint ventures with foreign shipbuilders and together undertake indigenous construction of the warships. In early December 2010, the Navy HQ issued its RFIs to Pipavav Defence & Offshore Engineering Company Ltd, Cochin Shipyard Ltd, Mazagon Docks Ltd, Garden Reach Shipbuilders & Engineers Ltd (GRSE), Larsen & Toubro Ltd, and the Vizag-based Hindustan Shipyard Ltd (HSL). These shipyards were required to forward a Detailed Project Proposal outlining the roadmap for the development of design and construction of the LPDs. After the RFI responses were submitted by March 7, 2011 the Detailed Project Proposal, thereafter, was examined by a Project Appraisal Committee (PAC) constituted by the MoD's Acquisition Wing to verify the credentials of the foreign partners, together with confirming the acceptability of the respective joint ventures between the Indian shipyard and its foreign collaborator. By September 2011, the Indian shipyards shortlisted for issue of the RFPs were intimated. The Request for Proposals (RFP), however, was issued earlier this month.
Foreign shipbuilders offering LPH solutions include DCNS of France with its Mistral-BPC 21,300-tonne LPH, Germany's ThyssenKrupp Marine Systems with its 20,000-tonne MHD-200 LPH (with two separate heli-decks on two levels), Fincantieri of Italy with its 20,000-tonne Mosaic LPH design, South Korea's Hanjin Heavy Industries & Constructions Co with its 18,800-tonne Dokdo-class LPH, and Navantia of Spain with its Athlas 21,560-tonne LHD. The favourite contenders are expected to be Navantia and Ficantieri.
A separate RFP will be issued in future for licence-building high-speed air-cushioned vehicles from either US-based Textron Marine and Land Systems (LCAC) or Hanjin Heavy Industries & Constructions Co (LSF-2), LCMs (with designs being offered by Navantia and Hanjin Heavy Industries & Constructions Co), or high-speed catamarans, for which France's CNIM is likely to offer its L-CAT catamaran.
A detailed analysis of the RFP for the LPH requirement brings out several interesting indicators about both the overall configuration of the desired vessel and its performance/operational capabilities. For instance, the RFP has specified that the length of the vessel should be 213 metres; the draught should not exceed 8 metres; the endurance at sea must be for 45 days; the propulsion system of should be of the integrated full-electric propulsion (IFEP) type; the vessel must have a suitable well-deck for carrying amphibious craft like LCMs or LCACs and LCVPs on davits and should have the capability to launch these craft when underway; the vessel must be able to house combat vehicles (including main battle tanks, infantry combat vehicles and heavy trucks on one or more vehicle deck; and the vessel should be able to undertake all-weather operations involving heavylift helicopters of up to 35 tonnes MTOW. Weapon systems and mission sensors to go on board the projected four vessels will all be pre-selected (known also as customer-furnished or buyer-nominated equipment). Such hardware will include the point-defence missile system (PDMS), close-in weapon system (CIWS), anti-torpedo decoy system, countermeasures dispensing system and 20mmmm heavy machine guns. In addition, each of the four vessels will be required to have one E/F-band combined air-surface surveillance radar, one C/D band air surveillance radar, and an integrated marine navigation system employing X- and S-band navigation radars.
The IN has finally zeroed in on integrated full-electric propulsion (IFEP) systems, starting with the four projected LPHs to be procured (one directly from a yet-to-be-selected foreign OEM, and three to be licence-built by a MoD-owned shipyard in cooperation with a private-sector shipyard). Present-day warships worldwide utilise a combined-diesel-and-diesel (CODAD), combined-diesel-and-gas (CODAG), combined-gas-and-gas (COGAG) or combined-diesel-Electric-and-gas (CODLAG) propulsion configurations. At cruising speeds a CODLAG system employs diesel generators to supply electricity to the electric motors that drive the propeller shafts. When high speeds are required, gas turbines engage the shafts via cross-connecting mechanical transmissions (gearboxes). In an IFEP system-equipped warship, on the other hand, there is no mechanical connection between the prime mover and shaft. Instead, both the gas turbines and diesels are configured as electricity generators. While the diesels provide the vessel's base load electrical supply, including low-speed propulsion, the turbines are switched in for peak power. The benefits of IFEP include: flexibility in locating machinery (only the propulsion motor needs to be coupled mechanically to the shaft-line); fuel efficiency (when the warship is operated at part load); low noise and vibration; built-in redundancy (electrical machines may have more than one set of windings, fed from different sources, so power is still available if one set fails); reliability (a mean-time-between-failures of more than 100,000 hours); reduced maintenance costs (due, for instance, to the absence of gearboxes); and the scope for increased automation and reduced crew complement.
The IN's LPHs will also employ fixed-pitch propellers. Controllable-pitch propellers and their associated complex hydraulics are not required since the motor, and thus the shaft, can be electrically reversed. However, the IN is against the procurement of podded propulsion systems—a point that could well go against the Mistral BPD-class LPH that DCNS of France is offering for the IN. It is thus widely expected that the IN will zero in on an IFEP system developed by UK-based but GE-led Converteam industrial consortium.
Coming now to the weapons suite, the IN has a choice of combinations to choose from, including the SeaRAM and Phalanx Block 1B from Raytheon, Sadral from MBDA integrated with OTOBreda of Italy's twin-barrel 30mm/82 Compact or the Goalkeeper from THALES Nederland, the combination of Phalanx Block 1B and Barak-1 from Israel Aerospace Industries, and the combined Palma PDMS/CIWS from Russia's Tulamashzavod JSC. It is believed that the Phalanx Block 1B/Barak-1 combination is the Navy's preferred choice. The Navy's shipboard decoy control and launching system of choice is the Kavach, which has been developed by the DRDO and is being built by Mahindra Defence. The combat management system and ELINT/EW suites will be procured off-the-shelf as standard fitment along with the LPHs.
