In today's world, CATOBAR has become a topic of increasing interest to people of all ages and backgrounds. Whether it is a historical event, a famous figure or a natural phenomenon, CATOBAR has captured the attention and interest of millions of people around the world. In this article, we will further explore the impact and relevance of CATOBAR, examining its origins, implications and influence on different aspects of everyday life. Through detailed analysis, we hope to shed light on this topic and provide a clearer view of its importance in today's world.
CATOBAR (“Catapult Assisted Take-Off Barrier Arrested Recovery") is a system used for the launch and recovery of aircraft from the deck of an aircraft carrier. Under this technique, aircraft launch using a catapult-assisted take-off and land on the ship (the recovery phase) using arrestor wires.
Although this system is costlier than alternative methods, it provides greater flexibility in carrier operations, since it imposes less onerous design elements on fixed wing aircraft than alternative methods of launch and recovery such as STOVL or STOBAR, allowing for a greater payload for more ordnance and/or fuel. CATOBAR can launch aircraft that lack a high thrust to weight ratio, including heavier non-fighter aircraft such as the E-2 Hawkeye and Grumman C-2 Greyhound.
The catapult system in use in most modern CATOBAR carriers is the steam catapult. Its primary advantage is the amount of power and control it can provide. During World War II the US Navy used a hydraulic catapult.
The United States and China are completing the development of electromagnetic catapult to launch carrier-based aircraft using a linear motor drive instead of steam. The electromagnetic catapult is found on the American Gerald R. Ford-class carriers (the electromagnetic aircraft launch system) and the Chinese carrier Fujian.
Following the decommissioning of Brazil's NAe São Paulo in February 2017, only three states currently operate carriers that use the CATOBAR system: the U.S. with its Nimitz-class and Gerald R. Ford-class, France with its Charles De Gaulle, and China with its Type-003 Fujian carrier.

The Chinese Fujian (Type 003) features an integrated electric propulsion system that will allow the operation of electromagnetic catapults, similar to the Electromagnetic Aircraft Launch System (EMALS) used by the United States Navy.
INS Vishal, India's second indigenous aircraft carrier of the Vikrant-class, is planned to be of 65,000 ton displacement and to utilize the EMALS catapults developed by General Atomics, as it supports heavier fighters, AEW aircraft and UCAVs that cannot launch using a STOBAR ski jump ramps.
