    Israeli system is not Integrated with Russian ones. The BARAK-8 has its own MFSTAR radar and fire controls. I don't see which equipment of Israel with which item of Russia the integration took place?

    Japanese are vassals of USA. Japan is not an independent country and its foreign policy is dictated by USA. We can't collaborate with Japanese without USA collaboration

    I don't understand this. Won't the submarine simply move away by the time time missile travels 600km? Very difficult to home in on submarines. Secondly, drones can use light weight torpedo to be dropped. There is no need for firing from 600km. Light weight tootsies have 15km range and with...

    Yes, that is what the idea is. Fire a missile and then make it submerge and hit the ship as a torpedo. It is something similar to ASROC of USA. But SMART is supersonic and has 600km range whereas ASROC is subsonic and has rocket range of 25km while the torpedo is a lightweight torpedo that has...

    Dornier is a design of a plane which is simple to build and efficient to operate. One can install any sensor on it according to needs. Dornier plane itself has nothing to do with sensors and it is just a plane with 19 seats.

    MiG29K engines are efficient and doesn't waste fuel. So, gas guzzler is not correct. Smoke is another issue but it is being said that latest engine variant has reduced smoke. Nuke carrier has advantage in long range Operations. But short range operations have advantage for diesel. Nuclear...

    We have Varunastra ready. But it is ship launched. MoD has already placed orders to BDL to manufacture it. Varunastra is being modified to be used in submarines. The project was announced in 2017. Once completed, the name of the Torpedo can be changed.

    Some of the points like heavier weight, higher complexity, slow speed and higher smoke & vibration is true. But the maintenance of diesel engine is significant lower than turbofan. Turbofans are maintenance heavy as the blades and moving components are under high stress. Tolerance of different...

    Lithium batteries are highly unsafe. They are only fit when condition can be controlled. None will use lithium batteries in such critical system like Submarines or aircrafts. Lithium batteries catch fire on slightest of problems.

    Why are you looking at USA ships? Indian ships use CODAG configuration most of the time where diesel engine is the main engine, not gas turbofan. Diesel engines of ships have efficiency of 50% whereas turbofan has 40%. LM2500 is a turbofan. India uses turbofan in most naval ships as secondary...

    Hull is simple WW2 Technology. The most important part is engine Integration and electronics. These consume a lot of time. Also, there is the make in India component which adds further to time

    How is this relevant? If you want electricity, go foe integrated electric generation? The problem with electric propulsion is that of extreme inefficiency. The conversion of heat to electricity rate at 35% and the further conversion of electricity to propulsion is 85-90% which will mean a total...

    Smaller ships will have lesser power generation and hence lower power radars. I don't know if such small ships can be used for air defence though they appear perfect for ASW and stealth offensive against enemy ships

    There ia a difference between electric propulsion and integrated electricity generation. Electric propulsion means that the electricity is produced to drive propulsion whereas integrated electric generation is generation of electricity from the main engine itself. This integration is useful in...

    Electric propulsion is inefficient compared to diesel as the energy has to be first converted to electricity and then used in motor. Converting heat into electricity has conversion factor of 35%. Converting Heat to propulsion has conversion factor of 50% in big & slow engines of ships. The only...

    Yes we are developing rapidly. I am only saying why we don't have indigenisation in high level for IAF but we have high indigenisation for navy & army. The reason being relatively higher Technology in IAF. PS - Helicopter carrier is a piece of shit. It is an insult to aircraft carriers to...

    Catapult & aircraft capable of flying from carrier is what makes carrier Technology high end. Without them, carrier is low end cement and steel. Making simple ski jump is not at all high Technology. About SSN, yes, India has developed the Technology and are going fast. Nevertheless, the...

    No, that will never happen. We are going to indigenise even the JV choppers. There is a deadline of 5 years for indigenisation. Even the engine will likely be supplied by HAL HTSE1200. So, there is no import lobby herebut just development of private industry. So, on one hand, PSU & DRDO will...

    We have not yet obtained catapult Technology or Technology for carrier aircraft. Nuclear submarine is a technology based on nuclear reactor in a submarine and was done by various countries as early as 1960. Even China did it by 1974. Moreover, we haven't yet got SSN but only SSBN which is simpler.
