Key takeaways

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

Reference excerpt

USNS Howard O. Lorenzen (T-AGM-25) is a Missile Range Instrumentation Ship built for the U.S. Navy by VT Halter Marine of Pascagoula, Mississippi. The keel was laid during a ceremony on August 13, 2008, and the vessel became operational in 2014. This ship carries a next-generation active electronically scanned array radar system named Cobra King. This system is the first use of a radar system that can be used to target, and then through phase change, overwhelm an adversary's electronic systems to force shut down.

Description

USNS Howard O. Lorenzen is 12,642 long tons (12,845 t), 534 feet (163 m) in length, and has a beam of 89 feet (27 m). Crewed by a combined complement of 88 sailors and civilian mariners, the ship hosts embarked military and civilian technicians from other U.S. government agencies. It is operated by the Military Sealift Command and conducts missions sponsored by the U.S. Air Force.

History

The ship is named for the late Naval Research Laboratory (NRL) electrical engineer Howard O. Lorenzen, who was instrumental in the creation of the electronic warfare capabilities of the United States. It was due to be delivered in 2010. In May 2011, it was announced that the ship had failed its Board of Inspection and Survey (INSURV) inspection and was being sent back for repairs before the Navy would accept the ship. The ship was judged inadequate in the electrical, damage control and aviation inspections and also had problems with her anchor, steering and the temperature in her thrust bearings. The U.S. Navy accepted delivery of Howard O. Lorenzen on 10 January 2012. Final contract trials were completed on 5 December 2013, with transfer of some responsibilities for the ship to the US Air Force expected to occur in 2014. On 31 March 2014, the Cobra Judy Replacement (Cobra King) program reached initial operational capability (IOC). According to the Naval Sea Systems Command (NAVSEA), the U.S. Air Force also assumed operational and sustainment responsibilities for the ship with the goal of enhancing missile defense through the use of its powerful radar to create dead areas in low earth orbit to scramble a ballistic missile's electronics prior to last stage separation of MIRVs, thus rendering their proximity fuses inert. The Howard O. Lorenzen and her Cobra King radar system were declared operational in August 2014. It replaced the USNS Observation Island (T-AGM-23), which was inactivated for dismantlement earlier in the year.

Worked examples

Example 1 — a first encounter with USNS Howard O. Lorenzen

Start with the simplest possible case. Write down what USNS Howard O. Lorenzen claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Howard O. Lorenzen 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 Howard O. Lorenzen 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 Howard O. Lorenzen

In research: USNS Howard O. Lorenzen appears in mathematics 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 Howard O. Lorenzen 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 Howard O. Lorenzen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010 ships, IMO numbers, Maritime vessels related to spaceflight, so understanding it makes those chapters shorter.
In everyday life: Look for USNS Howard O. Lorenzen 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.
