America’s largest unmanned aircraft is the RQ-4 Global Hawk

The RQ-4 Global Hawk is a high-altitude, long-endurance, remotely piloted aircraft with an integrated sensor suite that provides global all-weather, day or night intelligence, surveillance and reconnaissance (ISR) capability.

Northrop Grumman’s GLOBAL HAWK is one of, if not the world’s premier surveillance and reconnaissance unmanned aircraft system—and the Air Force’s go-to eye in the sky.

In the RQ-4 name, the “R” is the Department of Defense designation for Reconnaissance and “Q” means unmanned aircraft system. The “4” refers to the series of purpose-built remotely piloted aircraft systems.

The helicopters that submarines are most wary of are these ones (Video)

Image
Anti-Submarine Helicopters use specially-designed sensors and weapon systems to singlehandedly find, track, and even destroy submarines . One of the biggest fears of submarines are specially designed military helicopters developed with anti-submarine warfare capabilities. Such aircraft have grown enormously in the latest years. But how does a helicopter of this type work, and why are the most sophisticated products so efficient in their role? First of all, anti- submarine warfare helicopters  serve in naval environments, while they mainly operate on vessels (with a suitable hangar), alone, or with one more to two other similar aircraft. Their role is clear: anti-submarine warfare helicopters serve as aircraft that search, detect and track enemy submarines and underwater vehicles. Many of the most modern helicopters of this type can perform attack operations, although the payload limits its firepower. There are secondary tasks and missions that these aircraft can compl...

Iпcredible Velocity: Uпveiliпg the Astoпishiпg Wire Rope Splice Method iп a Remarkable Maпυfactυriпg Process (Video).

Image
The process of maпυfactυriпg iпdυstrial wire ropes is both iпtricate aпd fasciпatiпg, bυt perhaps the most impressive aspect of it is the fast wire rope splice method υsed to joiп the iпdividυal wires together. Iп this article, we will delve iпto the details of this amaziпg maпυfactυriпg process. Iпdυstrial wire ropes are made υp of mυltiple straпds of wire, which are twisted together to form a stυrdy, flexible cable. To joiп these straпds together, a process called spliciпg is υsed. Traditioпal spliciпg methods iпvolve paiпstakiпgly weaviпg each straпd together by haпd, which is both time-coпsυmiпg aпd labor-iпteпsive. However, the fast wire rope splice method revolυtioпizes this process, allowiпg for rapid spliciпg with little maпυal labor. The key to this method is a special machiпe that is υsed to twist the iпdividυal wires together with iпcredible speed aпd precisioп. First, the wires are fed iпto the machiпe, which grips them tightly aпd begiпs to twist them tog...

X reacts as comedy of errors decide Arsenal's victory over Liverpool

Earlier this season, Mauricio Pochettino quite rightly said: "Football is a game of mistakes." The Argentine's calamitous Chelsea side have done their best to prove him right but Arsenal and Liverpool delivered plenty of supporting evidence themselves on Sunday afternoon, with both teams benefitting from bone-headed blunders. Arsenal managed to come out on top in a truly chaotic contest, winning 3-1 to reignite their tilt for the Premier League title. Bukayo Saka's opener ensured that the Gunners have scored the first goal in each of their last four league matches against Liverpool - the first time Arsenal have achieved such a feat in this fixture since 1970. Played to a deafening soundtrack inside the Emirates Stadium, Arsenal were well worth their early lead, suffocating the visitors with a coordinated press. The Gunners had been just as sharp against Liverpool in the FA Cup last month but were painfully profligate in front of goal. Kai Havertz hadn't discovere...
