The ARH candidate by Bell is basically an improved Kiowa Warrior. It uses the same basic airframe as the KW, which is also based on the Bell Jet Ranger. It is longer, which allows more crew or gear to be carried, has more power and better engines, better avionics, etc., etc.
The MMS is not really used much anymore anyhow. It was designed for a battlefield full of Soviet armor, the KW was designed to hide behind the trees, spot and put a laser onto the tanks for artillery to shoot Copperhead laser guided projectiles at and for Apaches to shoot laser guided Hellfires at. Now that the AH-64D Longbow has better capabilities and uses radar guided Hellfires and the Copperhead is pretty much obsolete as well, the MMS is not really needed any longer. The FLIR mounted on the nose of the ARH is more capable than the MMS anyhow.
Also, Bell ARH has a 4-blade rotor system like the KW as well.
Bottom line, the KW is 1970's technology and it is time to change to an aircraft that better meets today's needs.
