FACTUALLY Incorrect and Hyperbola Bullshit. Poor Journalism
1. Scorpene will be delivered starting 2015 one every 6 months, all 6 will be delivered in 3 years.
2. Scorpene and Agosta 90 Both are different Generations of Submarines.
3. Indian did not Buy Scorpene because PN bought Agosta.
4. 3 Follow on subs will be built in addition to 6 already ordered.
Agosta 90B submarines are equipped with a SUBTICS fully integrated combat system. Agosta 90B submarine is fitted with four bow 533mm torpedo tubes and has the capacity to carry a mixed load of up to 16 torpedoes and missiles. The submarine can be equipped with the ECAN F17 mod 2 torpedo, which is a wire-guided torpedo with active and passive homing to a range of 20km. The torpedo delivers a 250kg warhead to a depth of 600m. Agosta 90B is equipped with the torpedo tube launched MBDA (formerly EADS Aerospatiale) Exocet SM39 missile. Target range and bearing data is downloaded into the Exocet's computer.
The missile approaches the target area in sea-skimming mode using inertial navigation and then active radar homing. The missile travels at speeds over Mach 0.9, and has a range of 50km. Exocet has a 165kg high-explosive shaped-charge warhead.

The system uses a masthead antenna array with omnidirectional and monopulse directional antennae and a separate periscope warning antenna
The submarine is fitted with a Thales Underwater Systems (formerly Thomson Marconi Sonar) TSM 223 sonar suite, which includes bow-mounted sonar and towed sonar arrays, SAGEM periscopes and navigation system and Thales I-band navigation radar. The diesel-electric system consists of two SEMT-Pielstick 16 PA4 V 185 VG diesels providing 3,600hp and a 2,200kW electric motor driving a single propeller. MESMA air-independent propulsion system, being fitted to the Agosta 90B submarines for Pakistan, allows the submarine to remain submerged three times longer.
The MESMA system consists essentially of a turbine receiving high-pressure steam from a combustion chamber, burning a gaseous mixture of ethanol and liquid oxygen. The Agosta 90B's performance remains the same in all other respects, except that the length increases from 67m to 76m and submerged displacement from 1,760t to 2,050t

Scorpene submarines
Scorpene is equipped with six bow-located 21in torpedo tubes providing salvo launch capability. Positive discharge launching is by an air turbine pump. The submarine's weapons include anti-ship and anti-submarine torpedoes and anti-surface missiles.
18 torpedoes and missiles or 30 mines can be carried by the Scorpene attack submarine. The handling and loading of weapons is automated.
SUBTICS combat management system, with up to six multifunction common consoles and a centrally situated tactical table, is collocated with the platform-control facilities.The combat management system is composed of a command and tactical data handling system, a weapon control system and an integrated suite of acoustic sensors with an interface to a set of air surface detection sensors and to the integrated navigation system. The system can also download data from external sources.The integrated navigation system combines data from global positioning systems, the log, depth measurement and the ship's trim / list monitoring system. The Scorpene monitors the environment including seawater density and temperature and the submarine's own noise signature.
The sonar suite includes a long-range passive cylindrical array, an intercept sonar, active sonar, distributed array, flank array, a high-resolution sonar for mine and obstacle avoidance and a towed array.
All submarine handling operations are carried out from the control room. The vessel features a high level of automation and surveillance, with automatic control mode of rudders and propulsion, continuous monitoring of the propulsion systems and platform installations, centralised and continuous surveillance of all potential hazards (leaks, fires, presence of gases) and the status of the installations that affect the safety while submerged.
The submarine incorporates a high level of system redundancy to achieve an average 240 days at sea a year for each submarine. The maximum diving depth is 300m, giving the commander more tactical freedom than previously available on conventional submarines. There is no limit to the duration of dives at a maximum depth, other than the power systems and crew limitations. The planning and design of the Scorpene was directed towards achieving an extremely quiet vessel with a great detection capability and offensive power.
The forms of the hull, the sail and the appendages have been specifically designed to produce minimum hydrodynamic noise. The various items of equipment are mounted on elastic supports, which are in turn mounted on uncoupled blocks and suspended platforms. The isolation also provides better shock protection to the equipment.
Scorpene has two diesel generation sets providing 1,250kW of power. At the top of the hull immediately above the diesel generator sets is a Dutch Breach machinery shipping hatch. The submarine has an elastically supported 2,900kW electronic engine.
There are two variants of Scorpene, the CM-2000 with the conventional propulsion system and the AM-2000 equipped with air independent propulsion. The AM-2000 is capable of remaining submerged on underwater patrol for three times longer than the CM-2000.
