The indians latest naval fleet have israeli radars on board and, like the chinese aegis, they are calling them indian Aegis. Now, if that type of radar is installed on mast at 5m height, then it will be able to detect aircraft flying at height of 20 to 30 m at distance of 27 k.m as curvature of earth changes after that.
This is what I have learnt from different defence fora.
Now this has an implication and important one.
Actually for aircrafts, it is very easy to fly very low over seas but at the same time, it is way much easier to detect them because of absence of clutter.
Now, if by satelite imagery, if their ships can be located in arabian sea, then it will be easy to avoid them and reach south but without the help of satelites, it will be too risky to go for the SOUTH mission even if the aircrafts are flying too low.
at 27 km the aircraft is toast. Seems like you missed it—-our missile range is190 km or farther.
We dont want to come close to the ships. They have ship to air missiles.
