To provide quality products and services with the efficiency and cost effectiveness our customers demand.


ILS-INC was founded as International Logistics Systems, Inc., by Walter Grinnell in 1989. Leveraging Grinnell’s more than 20 years of service in the U.S. Army in addition to his experience working for defense industry contractors such as Martin Marietta and Bowen & McLaughlin York, ILS-INC initially focused on providing Integrated Logistics Support (ILS) services as a Department of Defense (DoD) subcontractor. With such a rich history working on complex DoD contracts, today our experience has allowed us to expand into commercial markets. We proudly offer a wide range of services to meet the needs of clients in both defense and commercial sectors.


ILS-INC’s first major milestone was its award of a contract from York International (now part of Johnson Controls) to provide Integrated Logistics Support (ILS) on a significant naval systems project. ILS-INC founder and president Walter Grinnell credits York International’s A. L. Hershey for this opportunity. “We were very small,” but because of this contract, ILS-INC was able to become established in its iindustry. ILS-INC later worked with York International for various A/C plants for Navy ships for several years.

From this initial success, ILS-INC continued to develop teaming relationships, working as subcontractor alongside Bob Pressley of EG&G Technical Services (now URS Corporation) and Scott Meyers, who was president of General Dynamics Robotic Systems (GDRS). We maintain these professional relationships and have continued to expand our customer base and become diversified in who we work with as others find out about who we are and what we do.

“Our biggest marketing tool is our customers,” Grinnell said. Through our networking relationships, ILS-INC has worked on such notable contracts as the Semi-Autonomous Robotic Technology Integration (SARTI), Mobile Detection Assessment Response System (MDARS), and Ground Standoff Minefield Detection System (GSTAMIDS). ILS-INC has developed an exceptional reputation with our prime contractors as well as the Government Program Offices for providing quality products delivered on schedule for a low cost.

ILS-INC was the subcontractor to GDRS for the System Design and Development (SDD) phase of MDARS. ILS-INC was responsible for the technical documentation, training, and supportability engineering and further supported these aspects of MDARS throughout the Production phase.

In 2004, ILS-INC provided Outside Continental United States (OCONUS) training to soldiers for GSTAMIDS and Buffalo. The technical publications manager who supported the project described the experience as inspiring. “It was very rewarding to train in person overseas, to see our work put into application — into the soldiers’ hands.” The GSTAMIDS program manager who joined him said much the same. “We were sent to provide soldiers with equipment to help do their jobs and keep them safe. We helped to deliver, setup, train, and support initial operations. I believe a lot of our employees had a great sense of importance in our efforts and a great sense of pride in the work we provided to our troops when they really needed support.”

The training was well received. According to the technical publications manager, “The soldiers thought the equipment was worthwhile and applicable to what they were doing. They were happy with the technology that we brought over and found it extremely beneficial.” The experience also had a lasting impact on ILS-INC employees. After working with the soldiers directly, they have more respect for the job they do and the need for equipment we work on. The program manager remarked, “I have come to appreciate the job we provide to the government and, more importantly, to the soldier in the field. I was able to see the positive effects being made and the pride in our soldiers in the work they were doing. It gave me first-hand experience in the effects we as a company can have on so many lives that depend on us to provide the best support for them to safely understand, learn, maintain, and effectively utilize the equipment provided to them. Every day I look forward to working with our customers in meeting these challenges and improving support.”

ILS-INC’s direct soldier support efforts have since opened new doors for the company. ILS-INC was awarded a multi-million dollar subcontract for the Advanced Medium Mobile Power Sources (AMMPS) program. Our program manager for AMMPS said the contract brought ILS-INC a lot of growth. “It was an all-encompassing logistics effort,” he remarked.

Following AMMPS, ILS-INC secured a series of important projects operating out of the U.S. Army’s Tank-automotive Armaments Command (TACOM) and Tank Automotive Research, Development and Engineering Center (TARDEC) providing various ILS for the Interrogator Arm Assembly (IAA), Mine Resistant Ambush Protected (MRAP) vehicles, and construction equipment programs such as the Bituminous Material Paving Machine (BMPM). ILS-INC also secured contracts for the Basic Expeditionary Airfield Resource (BEAR) Power Unit (BPU), Entry Control Point Vehicle (ECPV) Joint Battlespace Command and Control System (JBC2S), and Linear Demolition Charge Systems (LDCS).

Most recently, we have supported AECOM Management Services’ Linear Demolition Charge System (LDCS), FLIR Systems, Inc.’s Common Robotics System – Heavy (CRS-H), Chemring Sensors and Electronic Systems’ Husky Mounted Detection System (HMDS), Precision Combustion, Inc.’s Platoon Power Generator (PPG), and Critical Solutions International’s Husky M1231.

Success Past, Present and Future

ILS-INC founder and president Walter Grinnell attributes the company’s success to the employees. “They all do an exceptional job. They are schedule oriented and have always performed and met requirements.” The company has a strong basis in teamwork. “Everybody helps everybody,” Grinnell proclaimed, and he feels this is a significant strength among the employees. Our Technical illustrator agrees. “Everyone works together, which is key,” he said. “A team who works together succeeds together.”

The ILS-INC team is not only successful but also proud of the company’s accomplishments, and employees are quick to boast about their work. “The Buffalo was in a movie,” our Technical Illustrator exclaimed. “It’s even a toy now. That’s cool. I actually sat in that thing when someone was driving it and got to see it built from the ground up.” Similarly, our Operations Manager said some of his most memorable experiences with the company were “being able to work with unmanned vehicles in the field and seeing how they can be utilized.”

This enthusiasm combined with ILS-INC’s past success is indicative of our future potential. Grinnell hopes to keep his original goals for the company thriving, to “continue to provide a good working atmosphere for employees and stability of employment” while delivering the high level of service our customers have come to expect.
