The Piaggio Aerospace P.1HH
HammerHead Unmanned Aerial System
The P.1HH
HammerHead UAS
The Piaggio Aerospace P.1HH HammerHead is a new, state-of-the-art Unmanned Aerial System (UAS) designed for Intelligence, Surveillance and Reconnaissance (ISR) missions whose combination of performance
and operational characteristics is at the very top end of the UAS MALE category.
An unmatched combination of range, wide operative speeds, fast climb gradient, high operative ceiling and
variety of payloads, provides end-users with a powerful yet flexible Defense System that outperforms other
MALE Systems, identifying the P.1HH HammerHead as a Super MALE UAS.
P.1HH HammerHead, is suited for a wide range of ISR, Defense and Security missions, and defines an unsurpassed mission role flexibility and sets a new frontier of CONcept of OPerationS (CONOPS) for Defense.
The P.1HH HammerHead Unmanned Aerial Vehicle (UAV) is derived from the successful Piaggio Aerospace
P.180 Avanti II business aviation aircraft, the fastest twin turboprop aircraft in the world with a proven, uneventful, service record of more than 20 years and 800.000 flight hours.
The design of the P.1HH HammerHead aims at being a unique ISR platform, able to climb up to 45.000
feet, loitering quietly at low speed (135 KTAS) for an endurance of up to 16 flight hours and dashing at very
high speed (up to 395 KTAS) to target. Its capabilities include being able to host several payload combinations and to perform multiple missions: aerial, land, coastal, maritime and offshore security, COMINT/ELINT,
electronic warfare as well as other roles.
Based on the P.180 Avanti II proven architecture and technologies (tested and certified for passenger
transportation) and, on the outstanding experience and capability of Selex ES in the mission management
systems for manned/ unmanned ISR, P.1HH HammerHead is designed to be an all weather aircraft with twin
turboprop propulsion providing maximum safety, operational reliability and the lowest incident rate in its category. The P.1HH HammerHead design is fully compliant with STANAG USAR 4671 standards to fly in both
restricted and unrestricted flight areas, according to the relevant authorities permission.

THE uav platform
The P.1HH HammerHead UAV platform has an aerodynamic configuration largely similar to P.180 Avanti II.
This is very versatile thanks to its unique patented 3 lifting surfaces configuration (3 LSC) and high aspect
ratio laminar wings, adapted for the P.1HH design by moderately increasing the wing span to sustain larger
vehicle masses and allocating a quick detachable joint to the outer wings for rapid aerial deployment of
the UAS in remote areas. Being based on a certified Mach 0.70 aircraft, P.1HH HammerHead is the fastest
MALE.
The P.1HH HammerHead power plant has two, highly reliable Pratt & Whitney Canada PT6A-66B turbine
engines integrated with low noise 5 blade scimitar propellers. The Power Plant is controlled by two Engine
Interface Units that receive commands from the FCC to drive the turbine and the propeller governors while
managing engine and propeller data. A large upper fuselage tank, supported by a robust yet efficient carry
through beam, is integrated to provide the required fuel quantity for long range and endurance.
A smart fuel system is designed to control and minimize the movement of the aircraft center of gravity for
