Royal Navy practice kept a new ship in trials until the service was satisfied enough to commission it. Before acceptance, the private yard remained responsible for defects and their cost. German practice commissioned ships sooner to raise reported fleet strength, shifting later repair responsibility to the navy once it owned the vessel. The contrast explains why an accelerated Tiger Cub still cannot be treated as operational the moment construction ends.
