The U.S. Army has halted the Armed Reconnaissance Helicopter program because development costs have almost tripled to $942 million from $359 million. In addition, deliveries were scheduled to begin in 2009 but had been pushed back to 2013. Army officials say they need helicopters now and will re-evaluate the requirements for a reconnaissance helicopter. In the meantime, the service branch will put more effort into the existing Kiowa Warrior fleet. The Army will implement a safety enhancement program to standardize that fleet and improve its effectiveness in combat. The upgrades include improved sensors, weapons systems and survivability equipment.
