The Pearl River Delta uses a variety of warning systems to inform the public regarding the risks of tropical cyclones to the area. The Hong Kong Observatory issues typhoon signals to indicate the existence and effects of a tropical cyclone on Hong Kong. The first numeric warning system was used in 1917.
[1] [3] When a system becomes a Category 3 hurricane with winds of between 96 and 112 kn (110 and 129 mph; 178 and 207 km/h), it is considered to be a major hurricane by the warning centers. [3] A Category 4 hurricane has winds of 113 to 136 kn (130 to 157 mph; 209 to 252 km/h), while a Category 5 hurricane has winds of at least 137 kn (158 mph ...
The TCWS system is the consequence of decades of evolution of early warning systems for tropical cyclones in the Philippines. The first tropical cyclone warning in the country was issued in July 1879. In 1931, the earliest formalized warning system for tropical cyclones was implemented by PAGASA's predecessor, the Philippine Weather Bureau. [5]

The Lockheed Martin Mk 70 Mod 1 is a containerized system containing four strike-length cells from the Mark 41 Vertical Launching System mounted in the footprint of a 40-foot (12 m) ISO container. [4] In addition to the Typhon system, the Mk 70 Mod 1 has been tested aboard ship on USS Savannah (LCS-28). [14]
The Japanese Zero fighter was the first to be produced in 1/48 scale and the first prop fighter added to the larger 1/32 scale in 2006 is once again the Japanese Zero. In 2023, Tamiya caught everyone by surprise with its announcement of a 1/48 F-35A Lightning II. [21] Tamiya has designed various kits and versions of the following airplanes in 1/48:
Praetorian DASS 1. Laser warners 2. Flare launchers (IR decoys) 3. Chaff dispensers 4. Missile warners 5. Wingtip pods for ESCM 6. Towed decoy . The EuroDASS Praetorian DASS is an integral part of Eurofighter Typhoon defensive Aid Sub-System (DASS) [1] providing threat assessment, aircraft protection and support measures in extremely hostile and severe environments.
The signal system was extended to ten signals (No. 1–10), although Signal No. 4 was only used in the Philippines but not in Hong Kong, as the non-local signals covered the information it conveyed. In 1935, the signal system was revised as agreed between the Observatory and the Central Weather Bureau of Manila.
