Overspill - energy on target but spills over target
Underspill - energy on target but spills before as well
Entrapment - no laser return. (spot inside room/cave, etc)
Specular reflection - laser energy is being reflected onto something creating a spot that is not the target
Podium effect - portions of the laser energy are blocked from the seeker view

5 laser seeker modes
Cage: inhibited from slaving or tracking
Stare: seeker along axis of missile body

5-10. The MQ-1C aircraft can carry the AGM-114 P+ and AGM-114R/R2 series of missiles. In the attack configuration four missiles are carried, and in the reconnaissance/attack configuration two missiles are carried. Both missiles incorporate an expanded engagement envelope from 180 to 360 degrees depending on the AVs altitude and software series. The P+ is currently being phased out as the R model is fielded. The R series of Hellfire missiles is the bridge to the Hellfire replacement which is the joint air to ground missile (JAGM). The R series comes in two versions, the AGM-114R and the AGM-114R2.

The AGM-114 R incorporates an integrated blast fragmentation sleeve (IBFS) warhead which is unique to the Hellfire family of missiles. This one warhead provides the commander with three capabilities. A high explosive anti-tank (HEAT) capability with a pre-cursor charge for attacking reactive armor equipped tanks and other hard targets, a blast fragmentation capability for light vehicles and personnel and a settable delay to allow the warhead to penetrate through a wall or ceiling and into a structure maximizing the overpressure feature of the warhead before detonation occurs.

The AGM-114R2 additionally incorporates a height of burst (HOB) capability which detonates the warhead approximately 3 feet prior to the missile impacting the target. This HOB capability provides an increased probability of kill (Pk) by eliminating the attenuation of the fragments by the ground.
Danger close for both series of missiles is 120 meters.

What are the AGM 114 series safety features?
Arming only after successful BIT, missile/launcher separation and fuze data received and safe separation signals received in correct sequence
Once armed, the ESAF device will not revert to the safe condition unless input power is removed from the main module
An out of sequence arm command event permanently inhibits the arming of the ESAF device during flight

Describe the action of the warhead before impact in the AGM 114 series
Arming sequence begins as missile is launched
28V passed to missile from aircraft immediately prior to launch. Controller CCA initiates a BIT of the ESAF device
After a successful BIT and when 15V of power is applied ESAF device checks for missile/launcher separation to occur
ESAF device monitors the longitudinal acceleration to determine if the safe arm distance has been reached
During missile/launcher separation and the attainment of the safe arm distance the ESAF device receives fuze data message from guidance section general purpose processor
This message is used to determine the detonation delay time between the precursor and main warheads
When the ESAF safe arm distance has been reached the arming process continues
ESAF device waits for a firing signal from impact sensor
When ESAF is armed the firing capacitors in the WFM and Main Module begin to charge
This sequence is complete before the motor is all burnt

"infrared fire and forget seeker"
and it was in 1992

HELLFIRE Imaging Infrared Seeker. The Imaging Infrared (IIR) seeker for the HELLFIRE Fire and Forget missile system requires a high data throughput with a low power, small, light weight processor. The use of VHSIC technology in the seeker and processor will result in a reliable, lowcost seeker with a long shelf life and a built-in test capability. The programmable/modular nature of the VHSIC components will accommodate future upgrades of missile capability. Development contracts for a VHSIC processor for the seeker were awarded in September 1985 to Texas Instruments and Ford Aeronutronics. At the beginning of 1987, development of the VHSIC processor hardware for insertion into the HELLFIRE IIR seeker was well under way. However, the Joint Service Seeker program, which was to furnish the sensor hardware for insertion into the HELLFIRE system, had been terminated. The HELLFIRE contracts are being modified to include the fabrication of a seeker heid utilizing residuals from the terminated Joint Service Seeker program. The resulting seeker and processor will make full utilization of VHSIC technology and are expected ito be completed during 1988.

..still seems some expensive overkill for small swarms and insufficient to protect against standoff helios and ground attack jets.

It really isn't a small swarm weapon. On IM-SHORAD it co-exists with the Stinger and the 30 mm gun and will eventually have a companion High Energy Laser option as well. Future interceptors will likely add to the envelope and focus on the higher end threats. So it isn't a one-size-fits-all approach which would be impossible to field affordably given the wide spectrum of UAS threats.

Moog_logo_202.jpg


Lockheed Martin was awarded a $15,925,901 modification to contract W31P4Q-18-C-0130 to develop a second source for the qualification and facilitization of the Electromechanical Control Actuation System for the Hellfire missile. Work will be performed in Orlando, Florida, with an estimated completion date of Aug. 28, 2021.


today MOOG Inc is single source for Control Actuation Systems

Good afternoon

I am wanting to build a 1:1 scale model rocket of the Hellfire Missile

Does anyone know where I can get some reasonably accurate drawings of one from
