The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform (aeronautics). The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns with 200 rounds per gun (rpg), two .30-caliber (7.62 mm) Brownings with 500 rpg, and a T1 Army Ordnance 23 mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25 mm Hotchkiss et Cie aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a M4 cannon with 15 rounds replaced the T1. The 15 rounds were in three five-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano-Suiza HS.404 20 mm (.79 in) autocannon with 150 rounds.

What was replaced in the YP-38s?
A: T1

Trying to snap a three-game losing streak, the Seahawks flew to Bill Walsh Field at Candlestick Park for a Week 8 NFC West rematch with the San Francisco 49ers.

The British also hoped that taking the well-known fort would boost troop morale and honour after their demoralizing battle defeat at Fort Ticonderoga in July 1758. In August 1758, the British under the command of Lieutenant-Colonel John Bradstreet left Fort Oswego with a force of a little over 3000 men and attacked Fort Frontenac. The fort's garrison of 110 men, commanded by Pierre-Jacques Payen de Noyan et de Chavoy, surrendered and were allowed to leave. Bradstreet captured the fort's supplies and nine French naval vessels, and destroyed much of the fort. He quickly departed to avoid further conflict with any French support troops. For the British, Fort Oswego was secured, and the army's reputation was restored. For the French, the fort's loss was considered to be only a temporary setback.'Fort Frontenac's surrender did not succeed in completely severing French communications and transportation to the west since other routes were available . Supplies could also be moved west from other French posts . In the long term, however, the surrender compromised French prestige among the Indians and contributed to the defeat of New France in North America. Since the fort was no longer perceived to be important to the French, it was never rebuilt and was left abandoned for the next 25 years. French imperial power was waning in the late 1750s, and by 1763 France had withdrawn from the North American mainland. Cataraqui and the remains of Fort Frontenac were relinquished to the British.

What fort's attack boosted morale after the British defeat at Fort Ticonderoga?
A:
Fort Frontenac
