Editing Peruvian Navy (section)

===20th century===
Following the War of the Pacific, the Peruvian Navy had to be completely rebuilt. In 1900 the force consisted of only one [[cruiser]] of 1,700 tons [[displacement (ship)|displacement]], a screw-driven [[steamboat|steamer]], and ten smaller ships – the latter described by a contemporary British publication as "of no real value".<ref>{{cite book|editor-last=Keltie|editor-first=J.

During the [[President of Peru|Presidency]] of [[Augusto B. Leguía]] (1919–1930) a Navy [[Ministry (government department)|Ministry]] was established as well as a [[Naval aviation|Navy Aviation Corps]], both in 1920.

Border conflicts with [[Colombia]] in 1911 and 1932 and a [[Ecuadorian–Peruvian War|war]] with [[Ecuador]] in 1941 saw Peruvian warships involved in some skirmishes in support of the [[Peruvian Army|Army]]. The [[attack on Pearl Harbor]] brought [[World War II]] to the Pacific and even though Peru did not declare war on the [[Axis Powers|Axis]] until 1945, its Navy was involved in patrol missions against possible threats by the [[Imperial Japanese Navy]] from early 1942 up to mid-1945.

During the 1970s and the first half of the 1980s the Peruvian Navy carried out a major buildup programme<ref>{{cite web|url=http://www.country-data.com/frd/cs/peru/pe_appen.html#table25|title=Armed Forces Strength in selected years, 1829 – 1992|access-date=February 21, 2015}}</ref> which allowed it to take advantage over its traditional rival, the Chilean Navy. The navy purchased one cruiser the [[BAP Almirante Grau (CLM-81)|BAP ''Almirante Grau'' (CLM-81)]] from the Netherlands, eight [[Carvajal-class frigate|''Carvajal''-class frigate]]s from Italy – four newly purchased and four ex-''Lupo''-class frigates – as well as six [[PR-72P-class]] [[corvette]]s from France. The buildup proved to be temporary due to the economic crisis of the second half of the 1980s, forcing the [[Ship decommissioning|decommissioning]] of several warships and resulting in a general lack of funds for [[Repair and maintenance|maintenance]].

The economic upturn of the 1990s and into the 2000s would later permit some improvement, although at a reduced force level compared to the early 1980s.{{Citation needed|date=May 2020}}
