[SIZE=3]Indian Naval Developments - Q2/1921[/SIZE]

A. Industrial Allocation

6/10 factories producing warship material = 6,000 t, plus a stockpile of 50 t, for 6050 t. 5851 t are used, leading to stockpile of 199 t.

4/10 factories dedicated to producing infrastructure material = 0.4 pts
“Bonus” infrastructure points for all 4 factories to be produced in Q4

B. Infrastructure Development

0.0 pts invested; Factory Eleven remains incomplete at 8.5 pts

C. Naval Construction

At Mumbai

D3: Collier/Carrier conversion Bhima receives 1000 t; completion scheduled 8/21

D1: Idle
Free-floating: CA Male receives 930 t; due to complete 5/12/21

Three 100 t motor torpedo boats are completed in commercial facilities.

D. Transactions

India transfers 0.4 pts of infrastructure points to South Africa as partial payment for BB Uruguay ; points are available for South African usage in Q3/21.

E. Other Notes

CA Bangalore ’s shakedown cruise continues
CL Columbo ’s shakedown cruise begins 6/5/21, ends 21/6/21
CL Jaipur ’s shakedown cruise continues.
DD G-128's shakedown cruise continues.

Purchase of the Uruguay is costing India 2.0 infrastructure points, with 0.4 pts paid in Q2, and Q3, and 0.8 pts being paid in Q4. 0.4 pts have been paid to date.

New units laid down this quarter: a seaplane tender, a monitor, a minesweeper, a sloop, and three torpedo boats.

The G131 class of destroyers is ordered, with an initial run of four to begin construction in Q3.

The Ordnance Board confirms that three new gun mounts will be installed and tested on the Chandragupta : a triple 9.8", a triple 5.9", and four twin 4.1" guns.

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

Note: X+(Y)+Z = completed (including shaking down) + (under repair/refit)+ under construction

BB: 1+(1)+0
