The Javelin was first built in 2751. The 'Mech quickly gained a reputation as a sturdy and reliable scout 'Mech. The Javelin weighs in at 30 tons but it has the maneuverability of lighter 'Mechs with a jumping distance of up to 180 meters. The Javelin does pay for this in the armor protection on its chassis, in some areas carrying armor weaker then the structure beneath. This drawback to the design does hamper it in pitched battle as the 'Mech cannot stand up to any degree of fire from a 'Mech heavier then it.
The Javelin caries a limited weapons array with two Arrowlite SRM 6 launchers with no backup weapons. This makes the Javelin highly reliant on a good supply line and can hamper the 'Mech if forced into guerilla combat.
