Frequent supply convoys in a fictional port scenario

Would a remote port need large supply convoys, and could Russia rebuild Kamchatka as a ship killer?

The suggestion is frequent smaller convoys because losing one large, infrequent shipment would leave the port in difficulty. Rebuilding Kamchatka as a ship killer depends on how such units arise in the setting.

For this fictional port, the suggested arrangement is frequent smaller convoys. The reason concerns the consequences of losing a shipment: an infrequent large convoy could leave the port in serious difficulty if intercepted and sunk. The exchange does not compare every escort or shipping-cost tradeoff, so the preference belongs to the proposed scenario. A separate Kamchatka ship-killer suggestion is judged plausible only subject to the setting's rules for creating such units.
