MK Machinery Technician (MK)

As of July 24, 2026, the best public Coast Guard rating table lists two documented Machinery Technician (MK) score paths: AR+MC+AS = 154 or VE+AR = 105. A later Coast Guard notice says non-diver A-school composites were adjusted while the current row-level list is internal, so treat 154/105 as public baselines and confirm the live requirement with a recruiter. MKs operate and repair engines, hydraulics, HVAC, and auxiliary machinery.

What this job pays as a junior enlisted member.

Base pay is set by pay grade, not by job — every Coast Guard enlistee at the same grade earns the same monthly base pay. These are the 2026 active-duty rates (3.8% raise, effective 2026-01-01).

Eligibility notes

What MK candidates should check.

  • COMDTINST M1500.10C Enclosure (3) lists two MK score paths: AR+MC+AS = 154 or VE+AR = 105. This page treats them as alternatives and presents both as documented public baselines.
  • Why public pages disagree: the Coast Guard announced in 2021 that composite requirements for every non-diver A-school were adjusted by 10 points while the component subtests stayed the same. It did not publish a complete replacement table, and COMDTINST 1500.10D now places the live row-level requirements in the internal PSC EPM-2 listing. Do not treat 154/105—or an inferred 144/95—as an uncaveated current guarantee; confirm the active MK requirement and waiver rules with a recruiter.
  • For the AR+MC+AS path, prepare Arithmetic Reasoning, Mechanical Comprehension, and Auto and Shop Information. For the VE+AR path, prepare Word Knowledge and Paragraph Comprehension (which form Verbal Expression) plus Arithmetic Reasoning.
  • The current Coast Guard MK career page and Yorktown school page both describe a 13-week rating course. That corrects the prior 18-week figure and does not include Coast Guard recruit training, A-school wait time, or optional follow-on C-schools.
  • The current MK career page describes work on internal-combustion engines, HVAC, hydraulics, and basic electrical systems. It also notes that MKs can serve at nearly every unit and that many train for law-enforcement boardings.

What is the AFQT minimum for MK Machinery Technician (MK)?

MK requires a minimum AFQT of 32 for Coast Guard enlistment.

Which line score does MK require?

MK requires one of these line-score paths: AR+MC+AS of at least 154 or VE+AR of at least 105, per U.S. Coast Guard COMDTINST M1500.10C Enclosure (3) (last verified 2026-07-24).

What ASVAB score do you need for Coast Guard Machinery Technician (MK)?

The best public Coast Guard rating table lists two MK paths: AR+MC+AS = 154 or VE+AR = 105. A later policy adjusted non-diver A-school composites, but the current row-level list is internal, so use 154/105 as documented public baselines and confirm the active number with a recruiter. Last reviewed July 24, 2026.

Is the Coast Guard MK ASVAB score 154/105 or 144/95?

M1500.10C publishes AR+MC+AS = 154 or VE+AR = 105. The Coast Guard later said non-diver A-school composites were adjusted by 10 points without publishing a complete replacement table. Because the live PSC EPM-2 list is internal, this page does not turn that blanket notice into an inferred 144/95 guarantee.

Do Coast Guard MK candidates need both listed score paths?

No. The public table uses “or”: AR+MC+AS = 154 or VE+AR = 105. This page therefore treats either public path as satisfying the documented score baseline, subject to the current internal list and recruiter confirmation.

Which ASVAB subtests should I study for Coast Guard MK?

The first public path uses Arithmetic Reasoning, Mechanical Comprehension, and Auto and Shop Information. The second uses Verbal Expression—built from Word Knowledge and Paragraph Comprehension—plus Arithmetic Reasoning. AR matters in both paths.

How long is Coast Guard MK A-school?

The current Coast Guard career and Yorktown training pages both describe a 13-week Machinery Technician rating course in Yorktown, Virginia. The 13 weeks cover MK A-school only; recruit training, wait time, and follow-on specialty schools are separate.

What does a Coast Guard Machinery Technician do?

MKs maintain and repair engines, pumps, hydraulics, refrigeration and HVAC equipment, outboard motors, and basic electrical systems on cutters and at shore units. The Coast Guard also says many MKs qualify for law-enforcement boardings.

What are the rating requirements for MK Machinery Technician (MK)?

The Coast Guard Machinery Technician (MK) rating (MK) requires a minimum AFQT of 32 and one of these line-score paths: AR+MC+AS of at least 154 or VE+AR of at least 105, with initial training of about 13 weeks. Those are the ASVAB-based entry requirements; a recruiter confirms the full enlistment picture (medical, background, and current openings).
