The FGM-148 Javelin consists of two separate components, the reusable Command Launch Unit (CLU) and the launch tube that houses the missile itself. The CLU consists of a body with a day site, thermal sight, hand grips, battery compartment, firing mechanism, and the interface that actually attaches the CLU to the launch.
To fire the Javelin, the user inserts a 5590 battery into the CLU to power it and places the launch tube to their side. The CLU is than turned upside down and connects the round interface connector at the top of the CLU to the metal hooks that receive it on the launch tube. Once locked in place, the entire system is rotated and hefted onto the soldier’s shoulder. The forward end cap on the launch tube is removed and the lens cover on the CLU is lowered.
The Javelin can be fired from the sitting, kneeling, or standing position. With some difficulty, it can be fired from the prone position, but care must be taken to ensure the soldier’s legs are clear of the backblast area which fans out at 60 degrees from the back of the launch tube when fired.
The soldier then looks into the CLU’s viewfinder and begins to identify targets on the battlefield. With an official maximum range of 2,000 meters, the thermal sight on the system helps the soldier pick out targets at night as well as through smoke and haze. Once an enemy armored vehicle has been identified, four-track gates inside the viewfinder are positioned over the vehicle to lock on to it.
The default mode of the Javelin missile is to fire in top attack mode which strikes the top of the vehicle, but the soldier can select the direct fire mode if the target is under overhead cover or to shoot down enemy helicopters. Locked onto a target, with the appropriate mode selected, the soldier squeezes the trigger on the handgrip to fire the missile.
The launch motor pushes the missile out of the launch tube before the flight motor kicks in and the missile takes off into the sky above the battlefield en route to the target that the soldier locked on to. As a fire and forget weapon, the soldier can now load a new launch tube and search for additional targets.
Meanwhile, small wings are deployed from the missile while in flight to help with stabilization as the guidance section tracks the enemy armored vehicle on the ground and transmits flight information. The guidance head on the missile continues to track the enemy armor as it moves across the battlefield while the missile maintains altitude until the flight control wings on cause it to angle downward towards the vehicle, striking from above where tanks and armored personnel carriers have the least armor.
The warhead on the missile has a precursor charge that detonates first to explode any reactive armor that the vehicle may be outfitted with before the main charges explode on impact, penetrating the hull of the vehicle.
The Javelin can be employed by a single soldier, but others will be needed to carry additional launch tubes, with each weighing about 35 pounds. These soldiers could be attached to an infantry unit to provide an anti-armor capability, but can work best when a number of Javelin teams are brought to together to form an anti-tank hunter/killer team that can provide mutually supporting fires on the battlefield.

Trainees can be taught how to fire the Javelin using the Basic Skills Trainer which consists of an inert Javelin system connected to a computer that transmits various scenarios into the CLU. Using this trainer, soldiers can be put through hundreds of different simulated scenarios where they have to rapidly load launch tubes, identify targets, lock on to them, fire, and then reload and reengage.
In 2015 and 2016, officials were still debating the merits of giving the Ukrainian military the Javelin for fears that it could provoke another Russian invasion. Bureaucrats argued amongst themselves as to how to mitigate the risk by engaging in games of semantics.
“Are we calling it lethal assistance or defensive assistance or defensive lethal assistance?” was the question being asked at the time the U.S. Military official said while shaking his head. From his point of view, it was an asinine debate as the Russians would know what a Javelin was regardless of what type of spin NATO and the Office of Defense Cooperation put on it.
A deal was worked out that they would call it defensive aid, with the prerequisite that the Ukrainians could only use it if fired upon first. Also, the weapon systems would be locked up in a secure facility, and only issued out to the military during an emergency. The Ukrainians shrugged off the conditions and dully agreed.
The first shipment of Javelins arrived in 2018, the weapons systems along with a training and sustainment block (called the Total Package Approach) totaling somewhere around 75 million dollars. “It takes like 18 months to get shit approved, then it spends six months on a boat,” the U.S. Military official complained, saying that we are way behind in providing training in assistance when other countries go to Russia and request fighter jets or helicopters and get them in a couple of weeks.

But the first shipment did arrive, and initial training was conducted by a contractor from Lockheed before the training program was taken over by the Security Assistance Training Management Organization (SATMO). This little-known organization has Warrant Officers, Master Gunners, and others on staff specifically to train foreign partner forces. Working with the Ukrainian military for six years, SATMO delivered an additional 200,000 pounds of lethal military aid to Ukraine in late 2021.
As the Russians learned that Ukraine now had Javelins, their T-72 tanks in Donbas became less aggressive, and pulled further back from the frontlines, the U.S. military official said.
Eventually, the Multinational Training Group-Ukraine was established in the Western part of the country, where battalions and then entire brigades were trained by the U.S. Military on a quarterly basis. Part of that training also included learning how to use the Javelin.
The U.S. Military source that Connecting Vets spoke to stated that the intelligence community was concerned about Russian troops on Ukraine’s borders starting in the summer of 2021 and that the Javelins themselves were likely taken out of the storage facility and issued to units that fall. With war breaking out in late February, initial reports indicate a weak Russian performance during the opening salvo of their campaign.
However, the numbers of tanks killed by Ukrainian soldiers, with the Javelin or other anti-tank weapons, are difficult to take seriously. Mostly appearing on social media, these numbers are likely to be exaggerated by the Ukrainians and downplayed by the Russians. The usual fog of war makes it even more difficult to ascertain accurate numbers.
However, a U.S. Special Operations official monitoring the conflict in Ukraine told Connecting Vets that he had seen estimates of 280 Russian armored vehicles taken out by the Javelin as of this writing, out of 300 total missiles fired.
