maximum operational flexibility in a wide range of mission payloads. The triple redundant 28VDC electrical
generation and distribution system supplies energy for all aircraft functions with adequate operational reserve
through the envelope, and fully satisfies large power demands from a variety of power consuming payloads.
P.1HH HammerHead inherits proven Piaggio Aerospace P.180 aircraft general system s, e.g.: Anti Ice, with hot
air on main wing, electrical on forward wing and pneumatic boots on the engine nacelle inlet. It also has a
hydraulic dual pressure system for landing gear extensions/retraction and brake activation, plus other
ancillary systems like fire extinguishing for the engine nacelle area. These subsystems are all commanded
by the VCMS, via fail-safe Remote Interface Units.

PAYLOAD ARRANGEMENT
The large but, low drag P.180 aircraft fuselage provides capability for aerodynamically effective payload
arrangements, with plenty of available volume from the variety of LRU’s equipment, sensors and communication equipment comfortably located inside the fuselage:

THE UAV BRAIN
P.1HH HammerHead features a technologically advanced Vehicle Control & Management System (VCMS)
that when combined with the advanced Mission Management System (MMS) manages the UAV and its
mission specific equipment.
The VCMS, commanded from the Ground Control Station (GCS) via an airborne datalink system, conducts the
vehicle commanding aerodynamic control surfaces and manages on-board equipment with a triple redundant
Flight Control Computer (FCC) system and multiple remote multi-lane Servo Interface Units (SIU), developed
to achieve the required level of safety and mission reliability.
Position, attitude and air data are guaranteed by triple redundant Inertial Sensors (INS) and
Air Data Probes (ADS), mounted in the VCMS.
P.1HH HammerHead VCMS features an Automatic Take-Off and Landing (ATOL) system served with dual
redundant external sensors for required reliability and safety.
All VCMS LRU’s are installed inside the large volume fuselage, in a very protected optimized operative environment, in a specific lay-out that provides zonal separation and temperature analysis to achieve a state of
the art operative temperature range, highest VCMS reliability and finally, P.1HH HammerHead safety. Very
easy access is provided through the large entry door and a multitude of access doors for the best maintainability within the segment.

Ground Control Station & DataLink System
An advanced Ground Control Station (GCS) is the P.1HH HammerHead UAS’s command & control center.
The GCS is located in an autonomous shelter that hosts crew, equipment and consoles necessary to manage
three UAVs (two operational, one in transfer mode) and their related Payloads.
The Crew processes functions necessary to execute tactical unmanned missions and stand-off surveillance unmanned missions, remotely commanding and controlling through VCMS and MMS the on-board surveillance
system with an advanced human/machine interface integrating display and control system.
The GCS is provided with multiple Ground Data Terminals (GDT) that when coupled with the associated Air
Data Terminals (ADT) on the vehicles provide Line Of Sight (LOS) and Beyond Line Of Sight (BLOS) Link for
Vehicle and Payload Control.
The Links System allows LOS & BLOS air vehicle command & control and payload digital encrypted data transmission via redundant, multi-frequency, high bandwidth RF links and via Ku/Ka Band SATCOM.
Mission data is eventually relayed to the headquarters either via ground communication systems or eventually
with the same LOS/BLOS data link.
VCMS / GCS is developed and supplied by Selex ES thanks to their long experience in Avionics for many different platforms and Unmanned Aerial Systems.
