USNS Coastal Crusader

USNS Coastal Crusader is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand USNS Coastal Crusader rather than just read about it. In short: USNS Coastal Crusader (AK-220/ORV-16/T-AGM-16/AGS-36) was an Alamosa-class cargo ship that was constructed for the US Navy during the closing period of World War II. She was later acquired by the US Army in 1946 and the US Air Force in 1957 before being reacquired by the USN in 1964 and as a missile range instrumentation ship.

Key takeaways

USNS Coastal Crusader belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect USNS Coastal Crusader to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of USNS Coastal Crusader from memory before moving on to harder problems.

Reference excerpt

USNS Coastal Crusader (AK-220/ORV-16/T-AGM-16/AGS-36) was an Alamosa-class cargo ship that was constructed for the US Navy during the closing period of World War II. She was later acquired by the US Army in 1946 and the US Air Force in 1957 before being reacquired by the USN in 1964 and as a missile range instrumentation ship.

Construction Coastal Crusader, a C1-M-AV1 cargo vessel, was laid down under a US Maritime Commission (MARCOM) contract, MC hull 2174, on 12 April 1945 at Sturgeon Bay, Wisconsin, by the Leathem D. Smith Shipbuilding Company; launched on 24 June 1945; sponsored by Mrs. DeForrest Colburn; and completed on 26 July 1945. On 25 February 1945, the Navy had assigned the name Wexford and the designation AK-220 to the projected ship; but the contract for her acquisition by the Navy was cancelled in August 1945 because of the cessation of hostilities in the Pacific Ocean and the surrender of Japan. Coastal Crusader thus entered mercantile service, never having borne the name Wexford.

US Army service The vessel was placed in service 30 August 1946, by the US Army Transportation Service as USAT Private Joe R. Hastings. She was returned to the Reserve Fleet on 27 October 1949.

US Air Force service Renamed Coastal Sentry, she was acquired by the US Air Force on 13 March 1957, which redesignated her an Ocean Range Vessel, USAFS Coastal Crusader (ORV-16). She operated on the Air Force's Eastern Test Range during the late 1950s and early 1960s.

US Navy service The US Navy acquired Coastal Crusader from the Air Force in 1964, a placed her in service with the Military Sea Transportation Service (MSTS) and redesignated her a Missile Range Instrumentation Ship, USNS Coastal Crusader (T-AGM-16). Navy records indicate Coastal Crusader was redesignated as a Survey Ship, Coastal Crusader (AGS-36) in 1969, and finally struck from the Navy List on 30 April 1976.

Inactivation Coastal Crusader was subsequently sold by the Maritime Administration (MARAD) on 12 April 1977. She was scrapped later that year.

Worked examples

Example 1 — a first encounter with USNS Coastal Crusader

Start with the simplest possible case. Write down what USNS Coastal Crusader claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to USNS Coastal Crusader before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about USNS Coastal Crusader ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of USNS Coastal Crusader

In research: USNS Coastal Crusader appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses USNS Coastal Crusader in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: USNS Coastal Crusader is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 ships, Alamosa-class cargo ships, Cold War auxiliary ships of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for USNS Coastal Crusader outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
