雨夜裡的M59加農炮 in 花蓮東大門夜市 DSC_1872-2

            The 155 mm Long Tom was a 155 millimeter caliber field gun developed and used by the United States mililtary. It was produced in M1 and M2 variants (later known as the M59). Developed to replace the Canon de 155mm GPF, the gun was deployed as a heavy field weapon during World War II and the Korean War, and also classed as secondary armament for seacoast defense. The gun could fire a 45.36 kg (100 lb) shell to a maximum range of 22 km (13.7 mi), with an estimated accuracy life of 1,500 rounds.

The Long Tom was also adopted by a number of other nations, including the United Kingdom, Austria, Israel, and the Netherlands.
美國參予第一次世界大戰時，發覺其陸軍極度缺乏新型野戰重炮，當時為了應急向法國購買授權生產的155公厘GPF加農炮，但是直到戰爭結束前參戰的美軍部隊使用的重型火砲沒有任何一門是美國製品，全部皆為外國貨。
第一次世界大戰後，1920年美國陸軍為了避免如同上次戰爭時發生的窘境，因此積極運作開發自製大口徑火砲，此時美軍向威斯特費爾特理事會（Westervelt Board）授命研發新型火炮，新型火砲採共通炮架，可安裝當時開發中的155公厘與203公厘火砲，而這次開發於1922年製造出M1920和M1920M1這兩款共通炮架火炮，在性能上雖然符合需求，但由於美國政府缺乏經費因此計劃遭到凍結。
計畫凍結了5年後，1927年獲得足夠經費計畫再次進行，此時除了共通炮架以外還增加了機械化高速牽引的需求，在1929年製造出了T2炮架，而對應炮架的155公釐砲管也持續研發（榴彈炮管計畫為T3，加農炮管計畫為T4），相關改良直到1938年才結束，而155公厘長砲管版本被定名為M1加農炮，此加農炮生產版本有M1A1、M1A1E1、M1A1E3、M2、M2E1，但是在外觀上這幾種衍生型皆沒有大幅度的改變，第二次世界大戰結束後，美軍在重新編號時將相關火炮通通納入M59此編號。
