AGM-114 Hellfire Missile
The family of Hellfire missiles includes, but is not limited to, AGM-114 B/K/K2/K2A/M/N/N-5/P/P+/R variants. These variants include shaped charge warheads (B/K/K2/K2A) for use against armored targets and blast fragmentation warheads (M/N) for use against urban structures. The AGM-114N is a thermobaric blast fragmentation warhead that maintains the capability provided by the AGM-114M while adding a unique capability against confined compartmented spaces, a typical target type observed in current combat operations. Other variants include the AGM-114 K2A which has a blast frag sleeve for use against soft-skinned tactical vehicles, the N-5 which provides a trajectory shaping capability to increase endgame lethality against vertical structures, the AGM-114P/P+ variants which include high-altitude launch trajectories for use from fixed-wing aircraft (such as the KC-130J Harvest HAWK), and the R which can be used against all Hellfire targets with a single warhead.
The latest Hellfire variant is the AGM-114R multi–purpose Hellfire II missile, (aka Hellfire Romeo). According to the U.S. Army, the AGM-114R will replace all other Hellfire II missile configurations (K/N/M/P). The AGM-114R consolidates the capabilities of all previous Hellfire missile variants. It is equipped with semi–active laser (SAL) seekers into a single missile capable of defeating a broad range of targets. The AGM-114R can be launched from multiple air, sea and ground platforms, autonomously or with remote designation. From pre-launch to detonation, the AGM-114R employs a range of technological improvements that boost its effectiveness and utility. The AGM-114R features a three–axis inertial measurement unit, which enables properly equipped launch platforms to engage targets to the side and behind without maneuvering into position. The AGM-114R can be launched from higher altitudes than previous variants due to its enhanced guidance system and improved navigation capabilities. A new multi–purpose warhead enables the missile to defeat hard, soft and enclosed targets, which allows pilots to engage many targets with a single Hellfire loadout. The Army is currently only purchasing this variant.

AN/AMS-2 integrated stormscope
Sikorsky Aircraft Company has given Charlotte-based Goodrich Corporation the nod for a long-term contract to provide an Electronic Standby Instrument System for the U.S. Army’s fleet of over 1,200 Black Hawk aircraft. The addition of this equipment is part of an upgrade of the fleet to the UH-60M helicopter and will also include Goodrich’s Emergency Power Supply and Stormscope lightning detection system.
Displaying lightning information at ranges out to 200 nmi, the Stormscope WX-500 is designed to interface directly with the Collins MultiFunction Display. Operating in a passive detection mode, the Stormscope locates thunderstorm activity by analyzing the radiated signals of electrical discharges from storm cells. Its ability to determine both azimuth and range is made possible through complex algorithms. These provide the reference information for the Stormscope to analyze the unique characteristics of the signals, their strength and their varying rates of recurrence. This information is then processed to determine the location and intensity of dangerous thunderstorm cells. Source aero-news.net
