The M15 class comprised fourteen monitors of the Royal Navy, all built and launched during 1915.
The ships of this class were ordered in March, 1915, as part of the Emergency War Programme of ship construction. They were designed to use the 9.2 inch Mk VI gun turrets removed from the Edgar-class and the Mk X turrets held in stock for the Drake-class and Cressy-class cruisers. This resulted in the first four of the class, which were built by William Gray & Company of Hartlepool, receiving the Mk X mounting. The remaining ten ships, all built by Sir Raylton Dixon & Co., Middlesbrough, all received the Mk VI mounting.
During September 1915, the 9.2 inch guns of HMS M24, M25, M26 and M27 were removed for use as artillery. These were replaced by 7.5-inch guns. M24 and M25 received the spare guns reserved for the recently sunk pre-dreadnought battleship Triumph, M26 received one of Swiftsure's spare guns. M27 received 6-inch (M27) guns.
M21 and M23 also had their 9.2 inch gun removed in 1917, receiving 7.5-inch guns from the decommissioned pre-dreadnought Swiftsure.
Monitor or monitor may refer to:
The Apple Monitor // is a CRT-based green monochrome 12-inch monitor manufactured by Apple Computer for the Apple II personal computer family. Apple did not manufacture the monitor until halfway through the lifespan of the II series. The business-line Apple /// had its own Apple Monitor /// long before. Many home users of Apple II computers used their televisions as computer monitors before the Monitor // was released. It featured an inner vertical-swiveling frame. This allowed users to adjust the viewing angle up or down to suit their taste without the addition of a tilt-and-swivel device. The Monitor // was widely adjustable for the time, as it included adjustments for the size and location of the image on the screen. These adjustments had a very small influence on the picture, however, much to the dislike of some users. The Monitor // was designed for the Apple II+, but was used widely throughout the Apple II product line, most recognizably on the Apple IIe.
