Operation Swordfish

Operation Swordfish 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 Operation Swordfish rather than just read about it. In short: Operation Swordfish or Operation Dominic Swordfish/Dominic-Swordfish was the May 11, 1962 operational test of the nuclear ASROC anti-submarine weapon system, as part of the larger Operation Dominic, a series of 31 nuclear tests. The ASROC uses a short range rocket booster to deliver a Mk 34 armed depth charge to the surface over the submarine target.

Key takeaways

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

Reference excerpt

Operation Swordfish or Operation Dominic Swordfish/Dominic-Swordfish was the May 11, 1962 operational test of the nuclear ASROC anti-submarine weapon system, as part of the larger Operation Dominic, a series of 31 nuclear tests. The ASROC uses a short range rocket booster to deliver a Mk 34 armed depth charge to the surface over the submarine target. The device sinks to a depth of approximately 650 feet or 235 meters where it would detonate with a yield around 10 kt of force. The RUR-5 ASROC was fired by the USS Agerholm (DD-826) about 370 nautical miles (690 km) west-southwest of San Diego.

Worked examples

Example 1 — a first encounter with Operation Swordfish

Start with the simplest possible case. Write down what Operation Swordfish 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 Operation Swordfish 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 Operation Swordfish 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 Operation Swordfish

In research: Operation Swordfish 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 Operation Swordfish 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: Operation Swordfish is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 in military history, Cold War anti-submarine weapons of the United States, May 1962 in the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Operation Swordfish 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.

Frequently asked questions

What is Operation Swordfish in simple terms?

Why does Operation Swordfish matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Operation Swordfish?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
