About

A defense-programs company built for sustained missions

Hemisphere Defense (HAD) is a defense-programs company that shares executive leadership with Hemisphere Aerospace Investments (HAI). Government missions increasingly require persistent awareness, distributed infrastructure, and autonomous-systems support delivered at a lower manpower burden and sustained over time. HAD is built to identify those operational gaps and develop disciplined programs around them.

We develop, manage, operate, and sustain the programs that support the mission. We approach each program with measurable criteria and decision gates, so capability advances on evidence rather than demonstration.

Why HAD Exists

A defense environment that increasingly requires persistent, distributed capability

Hemisphere Defense is the operating name of HEMISPHERE AEROSPACE DEFENSE, LLC, a defense-programs company based in Waco, Texas. The two names refer to the same registered entity. Hemisphere Defense shares executive leadership with Hemisphere Aerospace Investments (HAI).

Government missions increasingly depend on awareness that is maintained continuously, infrastructure that is distributed rather than concentrated, and autonomous systems that extend reach, all delivered at a lower manpower burden and sustained over a program's life. Hemisphere Defense is built to identify these operational gaps and develop structured defense programs around them.

Hemisphere Defense does not replace military services, government mission owners, or prime contractors, and does not hold government authority. HAD develops, manages, operates, and sustains the programs that support the mission.
Capability Areas

The mission requirements
HAD builds programs around

Persistent Awareness

Programs built around sustained sensing and monitoring, so awareness is maintained over time rather than demonstrated once.

Distributed Infrastructure

Capabilities designed to operate across dispersed locations and environments rather than depending on a single fixed point.

Autonomous Systems Support

Infrastructure that launches, recovers, hosts, and sustains autonomous and uncrewed systems in support of the mission.

Modular Mission Capability

Programs that adapt as sensors, payloads, and mission requirements change, without redesigning the underlying system.

Operational Sustainment

Maintenance, logistics, readiness, and lifecycle support treated as part of the program from the outset.

Rapid Program Development

Structured development against measurable criteria and decision gates, so capability advances on evidence.

In Brief

Hemisphere Aerospace Defense, answered directly

Short factual answers to the questions government mission owners, industry partners, and procurement teams ask first.

What is Hemisphere Aerospace Defense?

Hemisphere Aerospace Defense is a defense-programs company operating as HEMISPHERE AEROSPACE DEFENSE, LLC. It is registered in the System for Award Management under UEI JC89VWA2MA45 and CAGE code 22TR6, and is based in Waco, Texas. Hemisphere Defense is the company's operating name; the two refer to the same entity. It shares executive leadership with Hemisphere Aerospace Investments (HAI).

What does Hemisphere Aerospace Defense do?

Hemisphere Aerospace Defense identifies operational gaps in government missions and develops structured defense programs around them. The company develops, manages, operates, and sustains those programs across their life, rather than supplying individual components. Its work is organized around six capability areas: persistent awareness, distributed infrastructure, autonomous systems support, modular mission capability, operational sustainment, and rapid program development.

What mission areas does the company address?

Hemisphere Aerospace Defense works across land, air, and maritime domains. Ground programs address persistent awareness and support infrastructure in contested, remote, and austere environments. Air programs address reach, sensing, communications relay, and autonomous systems support. Maritime programs address persistent awareness, distributed sensing, and lower-burden operational coverage, and are where the company's first program is concentrated.

What is the Paul Revere Program?

The Paul Revere Program is persistent maritime awareness infrastructure designed to support maritime domain awareness, autonomous systems operations, modular mission capabilities, and government reach-back command. It is built around the AYDLL platform. It is infrastructure, not a ship, a weapons platform, or a replacement for crewed cutters, destroyers, or aircraft. The program is in program development.

Who develops the Paul Revere Program?

Hemisphere Aerospace Defense develops the Paul Revere Program. The program is the company's flagship effort and is built around the AYDLL platform.

How does Hemisphere Aerospace Defense approach autonomous systems?

The company treats autonomous and uncrewed systems as something its infrastructure supports rather than something it replaces people with. Its programs are designed to launch, recover, host, and sustain autonomous systems so those systems can operate for longer and further from shore-based support. The purpose is to reduce the burden of continuous, low-intensity sensing and monitoring on high-value crewed assets.

What authority remains with human operators?

Government personnel retain command authority, mission authority, intelligence authority, response authorization, engagement authority, and weapons-release authority where applicable. Hemisphere Aerospace Defense launches, recovers, hosts, operates, maintains, and sustains the infrastructure. The company does not replace military services, government mission owners, or prime contractors, and does not hold government authority.

Who leads Hemisphere Aerospace Defense?

The company is led by an executive team and a technical leadership team. Executive leadership comprises John B. Sawyer, Founder, Principal and Chief Executive Officer; Craig McPike, Brigadier General USAF Retired, Chair of the Board of Strategy and Oversight; and Alex Hart, Chief Financial Officer. Technical leadership comprises Robert Riedell, Director of Programs; Chip Fichtner, Head of Engineering; Dalton Sawyer, Technical Director; and Austin Fichtner, Technology Strategy and Integration.
