The ZAR began successfully tracking the target at 446 nautical miles (826 km) and properly handed off to a TTR. The TTR switched tracks from the missile fuselage to the warhead at 131 nautical miles (243 km). When the fuselage began to break up, the computer switched to clutter mode, which watched the TTR data for any derivation from the originally calculated trajectory, which would indicate that it had begun tracking debris. It also continued to predict the location of the warhead, and if the system decided it was tracking debris, it would wait for the debris and warhead to separate enough to begin tracking them again. However, the system failed to properly record when the warhead was lost, and tracking was never regained.

missile, meant that Zeus could only launch a small number of missiles at once. If the
Soviets also deployed MRV, even a single ICBM would cause several warheads to arrive at the same time, and Zeus would simply not have time to shoot at them all. They calculated that only four warheads arriving within one minute would result in one of them hitting the Zeus base 90% of the time. Thus one or two Soviet missiles would destroy all 100 Zeus missiles at the base. The RBIG noted that an ABM system "demands such a high rate of fire from an active defense system, in order to intercept the numerous reentry bodies which arrive nearly simultaneously, that the expense of the required equipment may be prohibitive". They went on to question the "ultimate impossibility" of an ABM system.

A variety of scenarios demonstrated that it was almost always the case that the offense had the advantage. The Air Force ignored this inconvenient problem while they were still working on Wizard, but as soon as the Army was handed sole control of the ABM efforts, they immediately submitted it to McElroy. McElroy identified this as an example of interservice fighting, but was concerned that the formula might be correct.

In one meeting with Edward Teller, Kennedy demonstrated that he knew more about the Zeus and ABMs than Teller. Teller then expended considerable effort to bring himself up to the same level of knowledge. Wiesner would later note that the pressure to make a decision built up until "Kennedy came to feel that the only thing anybody in the country was concerned about was Nike-Zeus."

782:, ensuring only a near miss could damage it. This would mean that the Soviets would have to launch at least one interceptor for each US warhead, while the US could launch multiple warheads without building a single new missile. If the Soviets added more interceptors to counter the increased number of US warheads, the US could counter this with a smaller number of new missiles of their own. The cost balance was always in favor of the offense. This basic concept would remain the primary argument against ABMs for the next two decades.

interceptor does not have to travel any further or faster, the computers that guide it simply have to select an intercept point farther in front of the target to compensate for the target's much higher speed.

This demands much larger and more powerful radar systems, and faster computers.

The actual engagement would normally take place at about 75 nautical miles (139 km) due to accuracy limitations, beyond that missiles could not be guided accurately enough to bring them within their lethal 800 foot (240 m) range against a shielded warhead.

Since the missile was designed to intercept its targets in space, it did not need the large maneuvering fins of the A model.
