Look for MIL-STD-167-2A(SH) (Notice 1 – 09 Feb 2023).
Department of Defense Test Method Standard: Mechanical Vibrations of Shipboard Equipment (Type I – Environmental and Type II – Internally Excited)
If you have a resonance Q-factor above 10, the standard allows "notching" (reducing input amplitude) only at specific frequencies, provided you prove the equipment can survive the amplified response. Do not notch arbitrarily. mil-std-167-2a pdf
Military standards are public documents, but they should always be sourced from official repositories to ensure you have the correct revision and any active notices or amendments.
The MIL-STD-167-2A standard is important for several reasons:
MIL-STD-167-2A categorizes vibrational threats into two distinct types, each with its own testing procedures and objectives. Understanding this division is crucial for proper application and compliance.
The MIL-STD-167-2A standard has applications in various industries, including: This standard applies to all shipboard equipment, including:
It specifically covers the vibration environmental requirements for shipboard machinery, equipment, and systems on surface ships and submarines. The "2A" revision is the current active version, superseding the original MIL-STD-167-2.
Compliance with MIL-STD-167-2A is non-negotiable for anyone manufacturing reciprocating machinery or propulsion components for the U.S. Navy. By downloading the official MIL-STD-167-2A PDF and embedding its balancing, torsional, and lateral vibration limits into your design lifecycle, you guarantee that your equipment can withstand the rigorous demands of naval service.
Ultimately, adherence to MIL-STD-167-2A is not merely about ticking a compliance box—it is about mission assurance, operational readiness, and, most fundamentally, the safety of the men and women who serve aboard naval vessels.
It is :
In the harsh and dynamic environment of naval operations, the reliability of shipboard equipment is not just a performance metric—it is a mission-critical requirement. One of the most pivotal documents governing this reliability is , the U.S. military standard specifically dedicated to the mechanical vibrations of shipboard equipment .

Dictates Type III, Type IV, and Type V vibrations. These apply directly to heavy powertrain dynamics, main propulsion lines, and large-bore reciprocating engines.
Conversely, equipment that successfully meets the standard’s requirements has demonstrated the ability to satisfactorily perform its intended functions while withstanding the demanding vibratory environment of shipboard operations. Military standards are public documents, but they should
Because this is a Department of Defense (DoD) standard with controlled distribution, it is not always hosted on public-facing commercial sites. You can verify its status or request access via official military document repositories:
