WEAPONS PLATFORMS

Naval & Maritime

Alion provides a fully integrated, total ship design and low-risk approach, with experience managing large engineering contracts focused on ship design, ship acquisition and shipbuilding, combat systems integration, and sustainment.

40 YEARS OF EXCELLENCE ON THE WATER

Alion is at the forefront of developing innovative design approaches and engineering solutions to address the technical challenges facing the 21st-century Navy. Our experience in total integrated ship system design is unparalleled, having supported nearly every major U.S. Navy ship design program for the past 40 years as well as a number of international shipbuilding programs.

Drawing on these four decades of naval architecture and maritime engineering experience, our staff includes certified acquisition and engineering professionals with extensive experience across all ship platform types and tasks. We have developed enduring relationships through our support of NAVSEA, its laboratories and field activities, and other government and commercial organizations. Our subject matter experts are known and trusted partners to their government counterparts.

OUR NAVAL & MARITIME SOLUTIONS

NAVAL
ARCHITECTURE

Our naval architects are proven experts in the design, development, and verification of complex ships, marine vehicles, and other marine structures against performance specifications.

g

MARINE SYSTEMS ENGINEERING

We lead the design and integration of mission-critical systems and components for optimization of function, space, weight, ruggedness, survivability, maintainability, cost, and performance.

STRUCTURAL ENGINEERING

We design the hull and internal structure for strength as well as other essential design considerations, including weight, producibility, cost, survivability, and more.

LIFECYCLE
SUPPORT

Alion engineers provide performance evaluation, support, repair, maintenance, and total ownership cost evaluation for systems and equipment throughout the entire service life.

FEATURED WORK

DDG 1000 DESIGN

Alion was the naval architect for the successful competition that resulted in the DDG 1000 class. Two industry teams were down-selected to compete for the design contract. The Navy specified a tumble-home wave piercing hull form, so both final designs were similar in appearance, but the successful design included several unique system and design features that were cited by the evaluators as discriminators. These included the peripheral vertical launch system (PVLS), the electrical power management system and all-electric propulsion, and composite deckhouse. These features either originated at Alion or were developed and verified by our team in the design process.

SSDG/GAS TURBINE DUCTING

The flat, oval design ship service diesel generator and gas turbine exhaust uptakes on LHD 8 have experienced cracking and structural failures. Both LHA 6 and DDG 1000 uptake installations were based on the LHD 8 designs and were at risk of similar failures. As part of the government team, Alion investigated the failures, developed a thermal data test plan, analyzed recorded thermal and dynamic response data, and determined that the root causes were related to thermal transients in the gas turbine duct and pressure fluctuations in the diesel generator duct. Design alternatives were investigated, and design requirements were subsequently revised based on our findings and recommendations.
