Richelieu-class battleship and more broadly the proximity between the two main artillery magazines (one for each turret), was the greatest risk: one hit could potentially neutralize the entire main battery, or even cause the ship's loss from an ammunition explosion. On "Dunkerque", to avoid this risk the forward turrets had been positioned apart from each other, further apart than on the "Nelson"-class battleships. The French also studied three-turret designs, such as one quadruple and two double, two triple and one double, or three triple. In every case, three turrets would have increased weight vs two quadruple turrets, reduced propulsion to and speed
Owned-and-operated television stations in the United States opened up a new spectrum of frequencies on the UHF dial (channels 14–83) for terrestrial television. As an incentive for companies to operate UHF stations, the FCC relaxed the ownership limit for a given entity from five to seven stations, provided that no more than five were on the VHF dial. With this opportunity to expand its roster of O&Os, NBC bought WBUF-TV (channel 17) in Buffalo in 1955 and WKNB-TV (channel 30) in New Britain, Connecticut (near Hartford) in 1957, and changed WKNB's call letters to WNBC-TV (the present-day WNBC in New York City used the WRCA-TV callsign from
