Why do the missiles keep spinning instead of going for the target?

Hello! I've recently come to a snag on this one missile heading script I've been working on. It technically works but it keeps going in circles instead of going toward the target. I've tried changing the radian? I'm not very good at CFrame math so I really don't know what I'm doing here. (partreg is a registry of important parts my game uses.)

local partreg = require(game.ServerScriptService.modules.partregistry)
while true do
    wait()
    for i,v in pairs(partreg.missiles) do
        if v ~= nil then
            local target = v:FindFirstChild('target')
            if target then
                local targeta = game.Workspace.ships:FindFirstChild(target.Value)
                if targeta ~= nil then
                    local targetpart = targeta.body.PrimaryPart
                    local inital = v.CFrame
                    local final = CFrame.new(v.Position,targetpart.Position) * CFrame.Angles(math.pi/.001,0,0)

                    v.CFrame = inital:lerp(final,i)
                    local angle = CFrame.new(v.Position, targetpart.Position)
                    v.AssemblyLinearVelocity = v.CFrame.LookVector * 200
                end
            end
        else
            partreg.removepart("missiles",v)
        end
    end 
end
