USS Wasp (CV-7) was a United States Navy aircraft carrier commissioned in 1940 and lost in action in 1942. She was the eighth ship named USS Wasp, and the sole ship of a class built to use up the remaining tonnage allowed to the U.S. for aircraft carriers under the treaties of the time. As a reduced-size version of the Yorktown-class aircraft carrier hull, Wasp was more vulnerable than other United States aircraft carriers available at the opening of hostilities. Wasp was initially employed in the Atlantic campaign, where Axis naval forces were perceived as less capable of inflicting decisive damage. After supporting the occupation of Iceland in 1941, Wasp joined the British Home Fleet in April 1942 and twice ferried British fighter aircraft to Malta.
A patrol boat is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine, estuarine, or river environments.

The British Mediterranean Fleet, also known as the Mediterranean Station, was a formation of the Royal Navy. The Fleet was one of the most prestigious commands in the navy for the majority of its history, defending the vital sea link between the United Kingdom and the majority of the British Empire in the Eastern Hemisphere. The first Commander-in-Chief for the Mediterranean Fleet was the appointment of General at Sea Robert Blake in September 1654. The Fleet was in existence until 1967.
The North American P-51 Mustang is an American World War II fighter aircraft.
P24 or P-24 may refer to:
p21Cip1, also known as cyclin-dependent kinase inhibitor 1 or CDK-interacting protein 1, is a cyclin-dependent kinase inhibitor (CKI) that is capable of inhibiting all cyclin/CDK complexes, though is primarily associated with inhibition of CDK2. p21 represents a major target of p53 activity and thus is associated with linking DNA damage to cell cycle arrest. This protein is encoded by the CDKN1A gene located on chromosome 6 (6p21.2) in humans.
P30 or P-30 may refer to:
HMS Sahib was a third-batch S-class submarine built for the Royal Navy during the Second World War. She was launched on 19 January 1942 and commissioned on 13 May 1942. She was the only British naval vessel to bear the name Sahib.

The Diciotti class is an Italian-designed offshore patrol vessel, presently in use with the Italian Coast Guard, Iraqi Navy, Armed Forces of Malta and Panama SENAN. These ships are designed and built by Fincantieri on the bay of La Spezia to Muggiano and Riva Trigoso shipyards.
The Protector-class coastal patrol boats are a class of coastal patrol boats of the Maritime Squadron of the Armed Forces of Malta. They are 87-foot (27 m) patrol boats based on the Stan 2600 patrol vessel design from the Netherlands shipbuilding firm Damen Group. The Hong Kong Police were the first organization to order vessels based on this design. The United States Coast Guard (USCG) has 73 patrol boats from this class, where they are known as the Marine Protector class. Malta ordered two vessels, and they were built by Bollinger Shipyards to the USCG specifications under the US$13 Million grant from the United States provided by the United States Securities Act of 2000. They were given pennant numbers P51 and P52. In 2013, both patrol boats were upgraded with new equipment including infrared cameras and a rigid hull inflatable boat. The upgrade cost €1.7 million and was co-funded by the European Union’s External Fund.
The P21 class is a class of inshore patrol vessels of the Armed Forces of Malta's Maritime Squadron. They are alternatively known as the Austal class after their builder.
The Maritime Squadron of the Armed Forces of Malta is the naval component of the Maltese military. The Maritime Squadron has responsibility for the security of Maltese territorial waters, maritime surveillance and law enforcement, as well as search and rescue. It is based at Hay Wharf in Floriana.
In U.S. education, deeper learning is a set of student educational outcomes including acquisition of robust core academic content, higher-order thinking skills, and learning dispositions. Deeper learning is based on the premise that the nature of work, civic, and everyday life is changing and therefore increasingly requires that formal education provides young people with mastery of skills like analytic reasoning, complex problem solving, and teamwork.
21st century skills comprise skills, abilities, and learning dispositions that have been identified as being required for success in 21st century society and workplaces by educators, business leaders, academics, and governmental agencies. This is part of a growing international movement focusing on the skills required for students to master in preparation for success in a rapidly changing, digital society. Many of these skills are also associated with deeper learning, which is based on mastering skills such as analytic reasoning, complex problem solving, and teamwork. These skills differ from traditional academic skills in that they are not primarily content knowledge-based.
