1In what year was the U.S. Coast Guard officially established under its current name?
A.1790
B.1915
C.1939
D.1967
Explanation: The U.S. Coast Guard was officially established under its current name on January 28, 1915, when the Revenue Cutter Service merged with the U.S. Life-Saving Service. While the Revenue Cutter Service was founded in 1790 under Alexander Hamilton, the modern Coast Guard name dates to 1915. The 1939 transfer moved the Lighthouse Service into the CG, and 1967 saw the CG move to the Department of Transportation.
2Which U.S. Cabinet department does the Coast Guard operate under during peacetime as of 2026?
A.Department of Defense
B.Department of Transportation
C.Department of Homeland Security
D.Department of the Treasury
Explanation: Since 2003, the Coast Guard has operated under the Department of Homeland Security (DHS) during peacetime. Before 2003, the CG was under the Department of Transportation (1967-2003). The Homeland Security Act of 2002 transferred the CG to DHS. During wartime or by presidential directive, the CG can be transferred to the Department of the Navy under the Department of Defense.
3Who is credited with founding the Revenue Cutter Service in 1790, the oldest predecessor of the Coast Guard?
A.George Washington
B.Thomas Jefferson
C.Alexander Hamilton
D.John Adams
Explanation: Alexander Hamilton, the first Secretary of the Treasury, is credited with founding the Revenue Cutter Service in 1790. Hamilton recognized the need for armed vessels to enforce tariff laws and combat smuggling along the U.S. coastline. The Revenue Cutter Service was the only armed maritime force of the United States until the Navy was re-established in 1798.
4Which major Coast Guard operation in the 1980s-2000s focused on drug interdiction in the Caribbean and Eastern Pacific?
A.Operation Arctic Shield
B.Operation Deepwater
C.Operation Steady State
D.Operation Noble Eagle
Explanation: Operation Steady State is the Coast Guard's ongoing counter-narcotics mission in the Caribbean Sea and Eastern Pacific, which expanded significantly in the 1980s and continues through 2026. CG cutters, aircraft, and law enforcement detachments (LEDETs) work with the Joint Interagency Task Force South (JIATF-S) to interdict drug trafficking. The operation has resulted in the seizure of hundreds of tons of cocaine and marijuana.
5The Coast Guard's response to Hurricane Katrina in 2005 is considered one of its finest hours. Approximately how many people did the CG rescue during that operation?
A.5,000
B.12,000
C.33,500
D.75,000
Explanation: The Coast Guard rescued approximately 33,500 people during Hurricane Katrina in 2005, making it one of the largest rescue operations in CG history. Coast Guard helicopters, boats, and personnel operated around the clock in extremely dangerous conditions. This operation demonstrated the CG's unique combination of maritime, aviation, and law enforcement capabilities and is widely studied as a model of disaster response.
6How many statutory missions does the Coast Guard have as defined by the Homeland Security Act of 2002?
A.5
B.8
C.11
D.14
Explanation: The Coast Guard has 11 statutory missions as defined by the Homeland Security Act of 2002. These are: ports/waterways/coastal security; drug interdiction; aids to navigation; search and rescue; living marine resources; marine safety; defense readiness; migrant interdiction; marine environmental protection; ice operations; and other law enforcement. These missions span both homeland security and non-homeland security functions.
7Which CG cutter class, introduced as part of the Deepwater program, serves as the backbone of the Coast Guard's offshore patrol fleet as of 2026?
A.Famous-class WMEC
B.Legend-class NSC
C.Island-class WPB
D.Bear-class WMEC
Explanation: The Legend-class National Security Cutter (NSC) is the flagship of the Coast Guard's offshore fleet, replacing the aging Hamilton-class high-endurance cutters. These 418-foot cutters have advanced sensors, C4ISR systems, and weapons capabilities. The Legend class was a centerpiece of the Deepwater modernization program. As of 2026, multiple NSCs are operational conducting drug interdiction, fisheries enforcement, and defense readiness missions.
8The Lighthouse Service was merged into the Coast Guard in what year?
A.1915
B.1939
C.1946
D.1967
Explanation: The U.S. Lighthouse Service was merged into the Coast Guard in 1939 under President Franklin D. Roosevelt's Reorganization Plan No. II. This merger added the aids to navigation mission to the CG's portfolio. The Lighthouse Service had been an independent agency since 1789, making it one of the oldest federal services. This consolidation gave the CG responsibility for all coastal navigation aids, lighthouses, and buoy tending.
9What is the Coast Guard's relationship to the U.S. Navy during wartime?
A.The CG becomes an independent military branch reporting to the President
B.The CG operates under the Department of the Navy per 14 USC
C.The CG is disbanded and members transfer to the Navy
D.The CG continues to operate under DHS with no change
Explanation: Per 14 USC Section 103, the Coast Guard operates as a service within the Department of the Navy upon a declaration of war or when directed by the President. This has happened during every major conflict since World War I. CG personnel, cutters, and aircraft come under Navy operational control while retaining their CG identity, regulations, and law enforcement authority. This dual-role capability makes the CG unique among the armed forces.
10Which historic Coast Guard operation involved the CG's role in landing craft operations during the D-Day invasion at Normandy in 1944?
A.Operation Torch
B.Operation Neptune
C.Operation Husky
D.Operation Overlord
Explanation: Operation Neptune was the naval component of the D-Day invasion on June 6, 1944, in which Coast Guard cutters, landing craft, and rescue flotillas played significant roles. CG-manned landing craft delivered troops to Omaha and Utah beaches, while CG rescue cutters saved hundreds of soldiers from the water. The CG's performance at Normandy earned the service widespread recognition for its combat capabilities and seamanship under fire.

Frequently Asked Questions

What is the Coast Guard Service-Wide Exam?

The SWE is the annual advancement exam for Coast Guard enlisted members seeking promotion from E-4 to E-5, E-5 to E-6, E-6 to E-7, and E-7 to E-8. It tests both general military knowledge and rate-specific technical knowledge. Scores are combined with performance evaluations, awards, sea time, and time in rate to produce a final multiple that determines advancement eligibility.

How is the SWE scored?

The SWE is scored by percentile ranking within each rate and pay grade. Your exam score is combined with performance marks, awards, sea time, time in rate, and other factors into a final multiple. Members are ranked against others in their rate competing for the same pay grade. Advancement quotas determine how many members advance each cycle.

What study materials should I use for the SWE?

The Coast Guard publishes a Professional Development Reference List (PDRL) for each rate and pay grade that lists all official study materials. The PDRL is updated annually and includes Commandant Instructions, Coast Guard publications, and federal regulations. Studying the PDRL thoroughly is the single most important preparation strategy.

When is the SWE administered?

The SWE is administered annually, typically in the spring. Exact dates are published via ALCOAST messages from Coast Guard Personnel Service Center (PSC). The exam is proctored at Coast Guard units worldwide. Members who are deployed or otherwise unable to take the exam on the scheduled date may be authorized a make-up exam.

What happens if I fail the SWE?

There is no pass/fail threshold on the SWE itself. Your percentile score is combined with other factors into a final multiple. If your final multiple is below the advancement cutoff for your rate and pay grade, you do not advance that cycle but can take the exam again the following year. Consistently strong performance evaluations and professional development improve your overall competitiveness.
