[SIZE=3]German Naval Developments - Q2/21 [/SIZE]

A. Industrial Allocation

6/11 factories to naval materials; 6,000 t created, plus a stockpile of 650, for 6650 tons. 6,493 of which is used, while 157 t is stockpiled

2/11 factories (committed) to infrastructure development

3/11 factories (non-committed) to infrastructure development; total 0.5 infrastructure points produced

B. Infrastructure Development

0.5 pts are used to further a Type 1 DD at Cuxhaven; 0.8 pts installed to date.

C. Naval Construction

At Wilhelmshaven

1 Type 2 drydock: CL Nymphe completes refit 5/21, drydock ready for Q3
1 Type 1 slip: idle
1 Type 0 slip: idle
1 Type 0 slip: idle
1 Type 0 drydock: idle

At Bremerhaven

1 Type 2 slip: CL Emden laid down 1/4/21, receives 1110 t, to complete 1/6/22
1 Type 1 slip: idle
1 Type 1 drydock: idle
1 Type 0 slip: idle

At Cuxhaven

1 Type 3 drydock: BB Markgraf receives 2,107 t; repairs to be completed 8/21
1 Type 2 slip: idle
1 Type 1 slip: idle
1 Type 0 slip: idle

At Kiel

1 Type 2 drydock: PD Hannover receives 1826 t; refit completes 31/5/21; drydock ready for Q3
1 Type 1 slips: idle
1 Type 1 drydock: idle
2 Type 0 slips: idle
1 Type 0 drydock: idle

Commericial shipyards build three 150 t coastal minesweepers.

D. Transactions

As per the Kobe Protocol, 1,000 t of warship material are delivered to Japan as compensation for the loss of the Augsburg . This material will be available on 1/7/22. In total, Germany owes 4,000 t of material to Japan.

E. Other Notes

As the refits to Hannover include modification of her secondary battery, the revised datasheet will be posted separately, shortly.

F. Updated Order of Battle, 30/6/21
