The QF 4.5-inch (110 mm) howitzer was used by British and Commonwealth forces in most theatres, by Russia and by British troops in Russia in 1919. Its calibre (114 mm) and hence shell weight were greater than those of the equivalent German field howitzer (105 mm); France did not have an equivalent.

4.7-inch gun M1920 on carriage M1920 [2] with 65-degree maximal elevation (the carriage was also designed to be used with 155-mm howitzer) weighing 13,000 pounds (5,900 kg). [5] 4.7-inch gun M1922E on carriage M1921E [2] of a similar design and same ballistics, but with 45-degree maximal elevation and lighter, just 10,600 pounds (4,800 kg).
The Type 730 is a Chinese seven-barrelled 30 mm Gatling gun/rotary cannon CIWS. It has a PLA Navy designation H/PJ12 . It is mounted in an enclosed automatic turret and directed by radar , and electro-optical tracking systems.
A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.
The RN was happy with the performance of the gun as it was significantly lighter than the standard 6 inch gun and fired an 82 lb shell rather than the 100 lb shell of the 6 inch weapon. It, therefore, had a higher rate of fire with little loss in hitting power. The British ordered more guns as secondary armament for HMS Furious and HMS Hood.

[3] [4] [5] For supersonic flight, drag increases at Mach 1.0 but decreases again after the transition. With a specifically designed aircraft, such as the (discontinued) Aerion AS2 , the Mach 1.1 range at 3,700 nmi is 70% of the maximum range of 5,300 nmi at Mach 0.95, but increases to 4,750 nmi at Mach 1.4 for 90% before falling again.
