On October 23, 2018, Dell introduced successors for both its semi-rugged and fully rugged 14-inch laptops. The new machines are the Latitude 5420 and 5424 Rugged on the semi-rugged side and the Latitude 7424 Rugged Extreme on the fully rugged end.
Dell Latitude Rugged 5420
It is a slenderized version of the Latitude 5424 Rugged that weighs less about 4.9 pounds (2.22kg) featuring IP-52 protection, MIL-STD-810G testing, can withstand drops from a height of 3 feet, and supports dust, anti-vibration, shock and moisture resistance, and can work at high altitudes and extreme temperatures. The new semi-rugged looks much like the previous one, but it has been changed and improved in numerous ways.
The Latitude 5420 Rugged has a 14-inch display. Standard resolution is full HD 1920 x 1080 pixel. Full HD was only available as an option on the predecessor 14 Rugged (it came with 1366 x 768 pixels). It has two smaller standard batteries, a more weight-saving design that is now hot-swappable, and the combined battery capacity is a bit larger than the old extended battery. Dell says the new design can reach 14 hours of battery life with dual batteries.

The Latitude 5424 Rugged is an entirely new design, the new machine is the same size as the old. It weighs almost a pound less, thanks to the smaller standard battery and more weight-saving design.

The specs suggest that all primary storage solid state disk options are of the PCIe NVMe variety with a 14-inch display. Full HD was only available as an option on the predecessor 14 Rugged. As the competition in this class, the Latitude 5424 Rugged offers excellent connectivity and expandability.
