The ground based aircraft and missile defense systems are used to effectively track, detect, intercept, and neutralize all kinds of air threats posed by combat projectiles, missiles, aircraft, rockets, and UAVs. These systems have the capability to defend a country from all incoming airborne threats.

Fuel cells are electrochemical devices that convert the chemical energy stored in fuel directly into electrical energy. Traditional gas generators create mechanical energy by combusting fuel and then convert the mechanical energy into electricity through generators. Fuel cells eliminate the need for additional conversion steps and provide usable electrical and heat energy directly from the stored chemical energy. They are used in marine vessels to power main propulsion systems partially or entirely and also cater to onboard energy consumption requirements.

Over 80% of the volume of international trade in goods is carried by sea, and the percentage is even higher for most developing countries. In 2020, maritime trade contracted by 3.8% reflecting an initial shock, but it rebounded later in 2021. IMO also forecasts that maritime trade could increase between 40% and 115% by 2050 in comparison to 2020 levels. Many factors influence this growth, including general economic conditions, rising population, increasing globalization. The continuous global economic growth is also spurring demand for shipments of energy products and other goods. In addition, growth in the manufacturing and industry sectors and improved socio-economic standards in emerging markets may increase demand for goods. With rising maritime trade, the demand for efficient and environment friendly marine engines used in these cargo ships are also expected to rise. Thus, driving the growth of the market
