How restrictive orders neutralize Scharnhorst's strength

Would additional Scharnhorst-class ships still be constrained by German orders against engaging the Royal Navy?

Yes; a blanket no-engagement order remains restrictive regardless of the squadron's numerical or tactical strength.

An order to fight only when victory looks likely would still leave room for tactical judgment. It might allow Admiral Luetjens to accept battle against HMS Renown when circumstances favored him. A blanket instruction to avoid engagement suppresses initiative regardless of force strength or opportunity. Political and command restrictions can therefore nullify the value of additional capital ships.
