7-shot Hydra-70 rocket pods, and an M296 0.50 in (12.7 mm) caliber machine gun. The performance standard of aerial gunnery from an OH-58D is to achieve at least one hit out of 70 shots fired at a wheeled vehicle away. The Kiowa Warrior also includes improvements in available power, navigation, communication, survivability, and deployability. OH-58F The OH-58F is an OH-58D upgrade. The Cockpit and Sensor Upgrade Program (CASUP) adds a nose-mounted targeting and surveillance system alongside the MMS. The AAS-53 Common Sensor Payload has an infrared camera, color Electro-Optical camera, and image intensifier; via weight and drag reductions, flight performance increased by 1–2%. Cockpit upgrades include the Control and Display Subsystem version 5, with more storage and processing power, three color multi-function displays, and dual-independent advanced moving maps. It has Level 2 Manned-Unmanned (L2MUM) teaming, the Force Battle Command Brigade and Below (FBCB2) display screen, and can be updated to Blue Force Tracker 2. Survivability enhancements include ballistic floor armor and the Common Missile Warning System. It has greater situational awareness, digital inter-cockpit communications, HELLFIRE future upgrades, redesigned wiring harness, Health and Usage Monitoring (HUMS), and enhanced weapons functionality via 1760 digital interface. The OH-58F is powered by a Rolls-Royce 250-C30R3 engine rated at ; it has a dual-channel, full-authority digital engine-controller that operates at required power levels in all environments. Rolls-Royce proposed engine tweaks to raise output by 12%. In October 2012, the first OH-58F was finished. Unlike most military projects, the Army designed and built the new variant itself, which lowered development costs. It weighed , below the target weight and about lighter than the OH-58D. The weight savings are attributed to more efficient wiring and a lighter sensor. The first production aircraft started being built in January 2013 and was handed over to the Army by year end. Low rate production was to start in March 2015, with the first operational squadron being fully equipped by 2016. The Army was to buy 368 OH-58Fs, with older OH-58 variants to be remanufactured. Due to battle damage and combat attrition, total OH-58F numbers would be about 321 aircraft. The OH-58F's first flight occurred on 26 April 2013. The Army chose to retire the Kiowa and end the CASUP upgrades. CASUP and SLEP upgrades was costed at $3 billion and $7 billion respectively. The OH-58D could do 20 percent of armed aerial scout mission requirements, the OH-58F upgrade raised that
