The Agusta Westland Lynx Wildcat reconnaissance helicopter is often criticised for having it's sensors mounted on it's nose.
Many believe a reconnaissance helicopter should have these sensors mounted above the rotor head in what is known as a Mast Mounted Sight (M.M.S.).
This is where the OH 58D Kiowa carries it's sensors.
Mounting the sensors up high allows the helicopter to see over cover while hovering behind it protected from enemy fire.
This was very useful during the Cold War when these helicopters were expected to be falling back on to friendly terrain ahead of advancing Soviet tank armies.
However,recent operations have seen American forces moving fast and high over terrain controlled by the enemy.
Seeing what is beneath the helicopter is now regarded as more important than hiding behind hills and you can't do that with an M.M.S..
Which is why the latest "F" model of the Kiowa Warrior will have it's sensors relocated to the aircraft's nose.
Just Like the Wildcat.
