A NEW CONCEPT IN MOBILE WEAPON SYSTEMS

World-wide need for light and inexpensive large caliber fire support weapon

Modularized system that is adaptable in multi-mission environments

Simplified design and operation to reduce crew size Simplified design to reduce maintenance time/life

cycle costs Reduced logistics support requirements Can be integrated to numerous vehicles Adaptable to international 105mm cannons of

different caliber length

WHY THE HAWKEYE?

NDIA 04 MAY 2017 02

The Hawkeye Weapon Systems was designed as a universal, world-wide howitzer which would provide highly mobile and lightweight

firepower to any army large or small.

Modular Multi-Platform Weapon System

Reduced Recoil Forces Reduced Crew Size Manufacturing Costs

Low Smaller Logistic

Footprint Electrically Operated

w/Manual Backup Emplace/Displace Time

DESIGN PARAMETERS

FT = MA

FT = (M1A1 M2A2)

CONVENTIONAL

SOFT RECOIL

Force of Run-up minus the Force of Recoil = Total Force (FT)

40-60% reduction in Recoil Force transferred to Carriage!

The importance of low recoil forces on carriages cant be over-stated

STRATEGIC DEPLOYABILITY

AIRCRAFT: C-130, C-17, C5A, Helicopters

CARGO SHIPS: Hawkeye small cube and lightweight

RAIL TRANSPORT: Fits narrow tunnels/bridges easily mounted to railcars

GROUND TRANSPORT: Small commercial trailers, military flatbed trucks

NDIA 04 MAY 2017 08

HMMWV/Hawkeye provides superior mobility due to light weight and fewer soldiers

Self-contained weapon system (one vehicle) for helicopter raids

Reduced logistics footprint: established vehicle (HMMWV) and simple weapon design

Quick emplacement during hasty maneuvers (Shoot and Scoot)

TACTICAL MOBILITY

NDIA 04 MAY 2017 09

Line Replacement Units easy to remove/install

Recoil Mechanism can be disassembled and rebuilt in a clean motor pool

Common Mechanics Tools no special tools required

Lightweight Components no need for heavy duty lifting devices
