OH-58D Kiowa Warrior (OH-58F Fox) Armed Reconnaissance Helicopter

The Armed OH-58D Kiowa Warrior, in service with the US Army, is supplied by Bell Helicopter Textron of Fort Worth, Texas. Around 375 Kiowas are in service and the single engine, double-bladed armed reconnaissance helicopter has been deployed in support of United States armed forces around the world including Haiti, Somalia and the Gulf of Arabia (Desert Storm and Desert Shield).

In 2002, Kiowas were deployed as part of Nato’s SFOR forces in Bosnia and, in 2003, 120 Kiowas were deployed in support of Operation Iraqi Freedom. 29 helicopters were lost during that operation. The US Army Kiowa fleet achieved a total of 750,000 combat hours until the end of 2011.


latest model, the OH-58D Kiowa Warrior, is primarily operated in an armed reconnaissance role in support of ground troops. The OH-58 has been exported to Austria, Canada, Croatia, the Dominican Republic, Taiwan, and Saudi Arabia. It has also been produced under license in Australia. Source wikiwand.com

OH-58D Kiowa Warrior armed Thereconnaissance helicopter role

The primary mission of the helicopter is in the scout attack role. The helicopter can be optionally equipped to carry out transport and utility roles using equipment kits installed externally on existing hard points.



A cargo carrying hook is rated to carry loads up to 2,000lb. Emergency casualty evacuation can be carried out transporting two casualties on litters (stretchers), plus over 320kg of supplies to an operating radius of more than 185km. The Kiowa can be used for insertion of up to six troops for critical point security missions.

Two Kiowas can be transported in a C-130 aircraft. For air transportation the vertical tail fin pivots, the main rotor blades and the horizontal stabiliser are folded, and the mast mounted sight, the IFF antenna and the lower wire cutter are removed. The landing gear can kneel to decrease the height.

Next-generation armed reconnaissance helicopter

The OH-58D Kiowa Warrior was to be replaced by the next-generation armed reconnaissance helicopter (ARH) within the US Army. A contract worth $211m for the ARH, a military version of the Bell 407, was awarded to Bell Helicopter in July 2005. Under the contract, Bell was required to supply 368 helicopters between 2008 and 2013.

In order to replace four Army National Guard attack helicopter battalions, the number of helicopters to be delivered was increased from 368 to 512. In July 2008, the US Army discovered that the ARH programme had exceeded cost-growth limits of the Nunn-McCurdy Act. The ARH programme was therefore terminated in October 2008.

Kiowa safety enhancement programme (SEP)

To maintain the safety and effectiveness of the Kiowa fleet until retirement, a safety enhancement programme (SEP) was launched as a part of the Army Scout refreshment programme in 1998. The SEP provided engine upgrades and improved computer control systems for 292 Kiowa helicopters. The programme was concluded in 2011.

In March 2009, the US Army awarded a contract to Bell Helicopter to upgrade an additional 27 OH-58D aircraft under the Kiowa Warrior SEP.

Upgrade work on the 27 aircraft began in April 2009 and deliveries began in the last quarter of 2009 at a rate of three aircraft a month. In March 2010 the US Army awarded a contract to modify the final 30 OH-58D aircraft under the SEP. Work on the final lot of aircraft in the SEP was started in March 2010 and completed in 2011. The upgrade was carried out at Bell Helicopter’s plant 1 facility in Fort Worth, Texas.

OH-58F Fox helicopter

In October 2010, the US Army provided the “Fox” designation to the upgraded version of OH-58D Kiowa Warriors. The new version is known is OH-58F or Fox and will have an upgraded cockpit and sensor. The upgraded fleet is expected to be deployed in the fourth quarter of 2015.

OH-58F Block II

OH-58 Block II demonstrator

Bell says the OH-58 Block II demonstrator “takes an OH-58 Kiowa Warrior and makes it a fast-fielding, low-risk and lowest-cost solution” to the Army’s expected “high-hot” operational requirement of 6,000-foot, 95-degree performance. That performance can be attained with propulsion and drive-train upgrades to the existing platform, the company says.

The Block II aircraft builds on the OH-58F-model cockpit and sensor upgrade program (CASUP) by adding a new Honeywell HTS900 engine, transmission and rotor system. The CASUP program replaces the OH-58D’s mast-mounted sensor with a nose-mounted sensor, updates the cockpit with color, multifunction displays, and incorporates full authority digital engine control and common missile warning system. As with the EADS candidate helicopter, the OH-58 Block II aircraft can be fitted with M3P machine gun, 2.75-inch rockets and Hellfire missiles. Source ainonline.com

Honeywell HTS900 engine

“The Honeywell HTS900 engine is a new type design engine to provide superior performance at high, hot conditions, fuel efficiency, and operating costs” said Mike Cuff, Honeywell Vice President, Helicopters and Surface Systems. “This certification demonstrates Honeywell’s continued success in developing the world’s highest performance turboshaft engines for both the commercial and military segments.

“The Honeywell HTS900 engine produces more than 1,000 Shaft Horsepower (SHP) uninstalled at sea level on a standard day – and has accumulated more than 1,000 flight hours,” Source aero-news.net

OH-58D cockpit


The Kiowa was the first US Army helicopter to have an all-glass cockpit. The cockpit is supplied by Sperry Flight Systems and is equipped with a multiple target tracking / moving target indicator, an ANVIS (aviation night-vision system) display symbology system and helmet-mounted display.

The primary multifunction displays provide situation information, communications control and the mast-mounted sight video. A video recorder stores television and thermal imagery from the mission and allows playback in the cockpit.


Kiowa weapons

The OH-58D is equipped with two universal quick-change weapons pylons. Each pylon can be armed with two Hellfire missiles, seven Hydra 70 rockets, two air-to-air Stinger missiles or one .50-calibre fixed forward machine gun.

LAU-68 rocket launcher w/ seven 2.75″ Hydra 70 rockets


Hydra-70 Family

Image: defenceindustrydaily.com

In the following, the nine main variants of the Hydra-70 rocket are presented:

M151 High-Explosive:

The M151 HEPD is a unitary fragmenting 10-pound anti-personnel, anti-material warhead with the M423 Point Detonating Fuze. Upon detonation, the warhead fragments into thousands of small high velocity fragments. The fuzed warhead is 16.2″ long and weighs 9.3 pounds.


The M156 white phosphorus (smoke) is primarily used for target marking. The M156 has the same ballistic characteristics as the M151 warhead and is of similar construction. Filler for the M156 is 2.2 pounds of white phosphorus with a 0.12 pound bursting charge of composition B. The fuzed warhead is 16.2″ long and weighs 9.65 pounds.

M229 High Explosive:

The M229 High Explosive warhead is a heavier version of the M151. The U.S. Army is currently not buying this variant. The fuzed warhead is 26″ long and weighs 17 pounds.

M255A1 Flechette:

The M255A1 Flechette warhead consists of a nose cone assembly, a warhead case, an integral fuze, 1,179 60-grain flechettes and an expulsion charge assembly. The primary fuze (M439) is remotely set with the Aerial Rocket Control System (ARCS) Multifunctional Display (MFD) or Rocket Management System (RMS) to provide a range from 500 meters to 7,200 meters. At expulsion, the 1,179 60-grain, hardened-steel flechettes separate and form a disk-like mass which breaks up with each flechette assuming an independent trajectory. The flechette uses kinetic energy derived from the velocity of the rocket to produce the desired impact and penetration of the target. The fuzed warhead is 26.9″ long and weighs 14 pounds.

M257 Illuminating Flare:

The M257 Illuminating warhead is designed to provide battlefield illumination and does not require the use of Infrared (IR) goggles. The M257 flare rocket can be launched by from either fixed wing or rotary-wing aircraft. The M442 motor burnout fuze functions after a 9-second delay. The fuzed warhead is 29.1″ long and weighs 11 pounds.

M261 Multi-Purpose Submunition (MPSM):

The MPSM warhead (weight is 13.9 pounds) provides improved lethal effectiveness against area targets such as light armor, wheeled vehicles, materiel, and personnel. The M73 Submunitions are deployed over the target and descend almost vertically. The M261 Warhead is a cargo warhead consisting of a nose cone assembly, a case, integral fuze, nine submunitions, and an expulsion charge assembly. The primary M439 warhead fuze is remotely set with the Aerial Rocket Control System (ARCS), Multifunctional Display (MFD) or Rocket Management System (RMS) to provide a range from 500 meters to 7,200 meters.

M264 RP Smoke:

The M264 RP (red phosphorous) Smoke is used as a red phosphorous filled smoke rocket propelled by the Mk 66 motor and the smoke is deployed at a range set remotely from within the aircraft cockpit. The M264 warhead is used for smoke obscuration in the visible light spectrum. The fuzed warhead is 26.9″ long and weighs 8.6 pounds.

M274 Smoke Signature (practice):

The M274 warhead is a smoke/flash signature practice warhead used for pilot/gunner training missions and consists of a cast iron warhead modified with vent holes, an aluminum nose cap with firing pin, a M423 fuze safe and arming device, and a smoke/flash cartridge. The fuzed warhead is 16.2″ long and weighs 9.3 pounds.

M278 Infrared Flare:

The M278 Infrared Flare warhead is designed for battlefield illumination for use with Infrared (IR) goggles. The flare rockets can be launched from either fixed wing or rotary-wing aircraft. The 442 motor burnout fuze functions after a 9-second delay. The fuzed warhead is 29.1″ long and weighs 11 pounds.

2.75-inch/70mm DAGR missile


The 2.75-inch/70mm DAGR missile is a precision-strike, multi-role, multi-platform munition that effectively neutralizes lightly-armored and high-value targets close to civilian assets or friendly forces. DAGR offers strike capability with the reliability of a HELLFIRE II missile while further limiting collateral damage.

The DAGR system puts HELLFIRE II missile and Joint Air-to-Ground Missile technology in a 2.75-inch guidance section that integrates seamlessly with legacy Hydra-70 rockets. Like HELLFIRE, DAGR offers lock-on-after-launch (LOAL) and lock-on-before-launch (LOBL) capability, target handoff, enhanced built-in testing on the rail, and laser coding from the cockpit. The result is a laser-guided missile that offers capabilities beyond those of a simple guided rocket.

The DAGR rail-mounted canister (RMC) mounts to HELLFIRE-compatible digital and analog launchers (e.g., M299/M310 and M272). The RMC readily integrates with all HELLFIRE platforms, including unmanned aerial vehicles and Apache, Kiowa, Little Bird, Cobra, and Tiger helicopters.

Plug-and-play HELLFIRE II compatibility allows aircrews to mix loadouts between HELLFIRE and DAGR missiles on the same launcher, providing the flexibility to meet any challenge on an ever-changing battlefield. When increased loadout or reduced weight is a must, DAGR delivers. Source lockheedmartin.com
